envSphere

Go to: Related nodes. Attributes.

The Env Sphere texture simulates an environment by mapping a texture or image file directly onto the inner surface of an infinite sphere. The best way to create a sphere environment is to use a ramp texture and paint objects onto it, being sure to avoid the poles and edges.

You can use the Env Sphere texture as a reflection map, by connecting its Out Color attribute to the Reflected Color attribute of an specular shader, such as Blinn or PhongE.

Aside from the attributes listed here, Env Sphere inherits additional attributes from TextureEnv.

In the table below, important attributes have their names listed in bold in the description column.

Long name (short name)	Type	Default	Flags
flip (f)	bool	false
Flip allows you to flip your input texture so that U and V are switched; the texture at the poles is moves to the equator and vice-versa.
image (so)	float3	0.5, 0.5, 0.5
Image is the texture or image that will be mapped to the inside of the sphere.
imageR (sor) float 0.0 The red component of Image
imageG (sog) float 0.0 The green component of Image
imageB (sob) float 0.0 The blue component of Image
infoBits (ib)	integer	0
Information bits passing along information about type of shading
pointCamera (p)	float3	0.0, 0.0, 0.0
The current sample point that has to be shaded
pointCameraX (px) float 0.0 The x component of the current sample position
pointCameraY (py) float 0.0 The y component of the current sample position
pointCameraZ (pz) float 0.0 The z component of the current sample position
refPointCamera (rpc)	float3	0.0, 0.0, 0.0
The current reference sample point that has to be shaded
refPointCameraX (rcx) float 0.0 The x component of the current sample position
refPointCameraY (rcy) float 0.0 The y component of the current sample position
refPointCameraZ (rcz) float 0.0 The z component of the current sample position
shearUV (suv)	float2	0.0, 0.0
Shear UV allows you to shear the texture along the longitude or latitudes of the sphere.
shearU (su) float 0.0 Shear U. Adjusting this will shear longitudinal lines. For example, straight vertical lines could be warped into a barber-pole arrangment.
shearV (sv) float 0.0 Shear V. Adjusting this will shear latitudinal lines. For example, lines that ran concentrically around the poles would spiral inwards.
