Description:
This is the base class for the creation of Sampler plug-ins which work with the Standard material. These appear in the Super Sampling rollout in the Sampler dropdown. They have an Enable checkbox and a Quality spinner for their user interface. An optional modal dialog may also be presented.

A Sampler is a plug-in that determines where inside a single pixel the shading and texture samples are computed. For some Samplers this pattern is the same for each pixel, for others a different pattern is chosen for each pixel. After determining the sample locations, the sampler calls back to the renderer to compute the shading values. It then averages the resulting shading values and returns its estimate of the final color.

Some Samplers are adaptive. This means that the Sampler decides on-the-fly how many samples to take to achieve its goal. There are many subtleties to adaptive Samplers and many ways to define the adaptive mechanism. The adaptive mechanism used by the R3 Samplers is very simple: take 4 samples, look for the maximum change in any of the color channels, if it's greater than the threshold, then sample the entire pixel according to the given quality. Threshold is an optional parameter that may, but need not be used by adaptive Samplers.

The transfer of control from 3ds Max to the Sampler plug-in is as follows: A Sampler is responsible for the sampling loop. It samples until it is done and computes the sum of its samples upon completion. Once the Sampler's DoSample() method is called 3ds Max no longer has control. This is how adaptive samplers are handled. The DoSample() routine will determine how often and where it samples, then it calls the provided SamplingCallback::SampleAtOffset() method to have 3ds Max compute the shading value.

◆ NotifyRefChanged()

RefResult NotifyRefChanged ( const Interval changeInt,
RefTargetHandle  hTarget,
PartID partID,
RefMessage  message,
BOOL  propagate 
)
inlinevirtual

Receives and responds to messages.

A plugin which makes references must implement a method to receive and respond to messages broadcast by its dependents. This is done by implementing NotifyRefChanged(). The plugin developer usually implements this method as a switch statement where each case is one of the messages the plugin needs to respond to. The Method StdNotifyRefChanged calls this, which can change the partID to new value. If it doesn't depend on the particular message& partID, it should return REF_DONTCARE.

  • For developer that need to update a dialog box with data about an object you reference note the following related to this method: This method may be called many times. For instance, say you have a dialog box that displays data about an object you reference. This method will get called many time during the drag operations on that object. If you updated the display every time you'd wind up with a lot of 'flicker' in the dialog box. Rather than updating the dialog box each time, you should just invalidate the window in response to the NotifyRefChanged() call. Then, as the user drags the mouse your window will still receive paint messages. If the scene is complex the user may have to pause (but not let up on the mouse) to allow the paint message to go through since they have a low priority. This is the way many windows in 3ds Max work.
Parameters
changeInt- This is the interval of time over which the message is active. Currently, all plug-ins will receive FOREVER for this interval, with the exception of REFMSG_FLAGDEPENDENTS notifications. In that case, changeInt.Start() is the timepoint to perform the dependency test.
hTarget- This is the handle of the reference target the message was sent by. The reference maker uses this handle to know specifically which reference target sent the message.
partID- This contains information specific to the message passed in. Some messages don't use the partID at all. See the section List of Reference Messages for more information about the meaning of the partID for some common messages.
message- The message parameters passed into this method is the specific message which needs to be handled.
propagate- If called through ReferenceMaker::NotifyDependents(), the value of 'propagate' passed to it. Used if calling NotifyDependents() from within NotifyRefChanged().
Returns
The return value from this method is of type RefResult. This is usually REF_SUCCEED indicating the message was processed. Sometimes, the return value may be REF_STOP. This return value is used to stop the message from being propagated to the dependents of the item.

Implements ReferenceMaker.

91 { return REF_SUCCEED; }
@ REF_SUCCEED
The operation succeeded.

◆ SuperClassID()

SClass_ID SuperClassID ( )
inlinevirtual

Retrieves a constant representing the type of the plugin.

Returns
A super class id that uniquely identifies the type (category) of the plugin. Note that several plugin classes can be of the same type, thus return the same super class id. Plugins are uniquely identified by their class ids.

◆ DoSamples()

virtual void DoSamples ( ShadeOutput pOut,
SamplingCallback cb,
ShadeContext sc,
MASK  mask = NULL 
)
pure virtual
Remarks
This is the method where the Sampler plug-in does its sampling loop. Upon completion it returns the color and transparency back to 3ds Max in c and t.

A sampler samples a range of 0.0 to 1.0. For a pixel sampler this range gets mapped to a single pixel. The sampler doesn't need to be concerned with this however. It just works within the 0.0 to 1.0 space determining where to put the samples. Essentially, this method generates a set of points and calls SamplingCallback::SampleAtOffset() for each one. Then it sums up the results of the values returned from SampleAtOffset(), divides by the number of samples, and stores the results in c and t.
Parameters:
ShadeOutput* pOut

This is the output of the sampling.

SamplingCallback* cb

This is the callback provided by 3ds Max which the sampler uses to actually do the sampling.

ShadeContext* sc

The Shade Context which provides information about the pixel being sampled.

MASK mask=NULL

The 64 bit pixel mask. This mask coresponds to the 8x8 sub-pixel area grid. The actual geometry covers only some portion of these bits. This is essentially an 8x8 raster for the inside of the pixel where bits are set over the polygon being rendered and bits are off for areas not over the polygon. Developers typically only want to sample where the geometry is and thus when the bits are on. If not the results are very poor visually.

Note: Most polygons are quite small in a typically complex scene being rendered. In other words, most polygons that need to get sampled will only have a small number of these mask bits on since the polygons are very small relative to the pixel. For instance, edge on polygons may project down to only a few bits within the pixel. Consequently it is quite possible that there may be zero samples, i.e. no geometry in the mask. Developers need to check for this zero samples condition. If this is the case then a method of ShadeContext called SurfacePtScreen() is used. This method returns a point which is guaranteed to be on the fragment no matter how small it is. This point can then be used for at least a single sample.
Sample Code:
The following is a brief analysis of the DoSamples() method from the Uniform Sampler of 3ds Max. This sampler sub-divides the sample area into a grid and samples the pixel at the center point of each grid unit.

This code is from the file /MAXSDK/SAMPLES/RENDER/SAMPLERS/STDSAMPLERS.CPP.

The complete code is shown below and then a code fragment analysis follows:

void UniformSampler::DoSamples( ShadeOutput* pOut, SamplingCallback* cb, ShadeContext* sc, MASK mask ) {
int sideSamples = GetSideSamples();
DbgAssert( sideSamples > 0 );
// we map 0...sideSz into 0..1
float sideSzInv = 1.0f / float(sideSamples);
float sampleScale = texSuperSampleOn ? sideSzInv : 1.0f;
Point2 samplePt;
float nSamples = 0.0f;
pOut->Reset();
ShadeOutput sampOut( sc->NRenderElements() );
// Sampling Loop
for( int y = 0; y < sideSamples; ++y ) {
samplePt.y = (float(y) + 0.5f) * sideSzInv;
for( int x = 0; x < sideSamples; ++x ) {
samplePt.x = (float(x) + 0.5f) * sideSzInv;
if ( sampleInMask( samplePt, mask, sc->globContext->fieldRender ) ) {
// returns true for unclipped samples
if (cb->SampleAtOffset( &sampOut, samplePt, sampleScale )) {
(*pOut) += sampOut;
nSamples += 1.0f;
}
}
}
} // end, sampling loop
if ( nSamples == 0.0f ) {
// gets center of frag in screen space
samplePt = sc->SurfacePtScreen();
cb->SampleAtOffset( pOut, samplePt, 1.0f );
}
else {
pOut->Scale( 1.0f / nSamples );
}

ULONG MASK[2]
Definition: samplers.h:20
The above code is broken into smaller fragments to look at below:

int sideSamples = GetSideSamples();
Here the sampler is just getting the number of sides in the sampling grid. This is computed based on the Quality spinner in the user interface. In this sampler this results in a number between 2 and 6 (developers can look at the UniformSampler::GetSideSamples() method to see this). Thus the resulting sampling grid is 2x2 or 3x3, up to 6x6. Then the number of samples is computed by multiplying the number of sides times itself.

int numSamples = sideSamples * sideSamples;
Next the side size inverse is computed to know how big the step size is. This is the amount to step along each time.

The sample scale is how large is the piece that's being sampled. For example, if the grid is 2x2 then each sample is scaled by 1/2

float sideSzInv = 1.0f / float(sideSamples);
float sampleScale = texSuperSampleOn ? sideSzInv : 1.0f;
Next the number of samples, and the color and transparency are initialized to zero:

float nSamples = 0.0f;
pOut->Reset();
ShadeOutput sampOut( sc->NRenderElements() );
Then the sampling loop begins. Here the positions of individual sampling points are computed. Each point is then checked to see if it corresponds to a point in the mask (is over a polygon). (The sampleInMask function is defined in /MAXSDK/SAMPLES/RENDER/SAMPLERS/SAMPLERUTIL.CPP). If it is a point that's over a polygon then SampleAtOffset() is called. What SampleAtOffset() does is turn the passed 2D sample into a 3D sample and fills out a ShadeOutput with a color and transparency. These returned values are summed up over the sampling loop ((*pOut) += sampOut;).

for( int y = 0; y < sideSamples; ++y ) {
samplePt.y = (float(y) + 0.5f) * sideSzInv;
for( int x = 0; x < sideSamples; ++x ) {
samplePt.x = (float(x) + 0.5f) * sideSzInv;
if ( sampleInMask( samplePt, mask, sc->globContext->fieldRender ) ) {
// returns true for unclipped samples
if (cb->SampleAtOffset( &sampOut, samplePt, sampleScale )) {
(*pOut) += sampOut;
nSamples += 1.0f;
}
}
}
}
At the end of the sampling loop a check is done to see if there were zero samples. This is the case if the geometry is very small relative to the pixel. There are two approaches that one might take when there are zero samples. One is to simply return black. A strict 'jitter-type' sampler might do this since, in fact, no samples were hit. This will result in artifacts to the image however. A better approach is to use the ShadeContext method SurfacePtScreen() to return a point which is guaranteed to be at the center of the fragment. Then this point is passed to SampleAtOffset() so a single sample which is on the fragment is used.

If a single sample point was used, DoSamples() is finished. The reults are in pOut as returned from SampleAtOffset().

If a number of samples was taken, the shade info is scaled by the inverse of the number of samples (nSamples) to get the final colors.

if ( nSamples == 0.0f ) {
// gets center of frag in screen space
samplePt = sc->SurfacePtScreen();
cb->SampleAtOffset( pOut, samplePt, 1.0f );
}
else {
pOut->Scale( 1.0f / nSamples );
}
