General MNMesh Component Flags | |
| #define | MN_SEL (1<<0) |
| For MNVerts, MNEdges, and MNFaces, bits 0-7 are used for common characteristics of all components. | |
| #define | MN_DEAD (1<<1) |
| Indicates that a component is not used and should be ignored. | |
| #define | MN_TARG (1<<2) |
| Indicates that a component is targeted. | |
| #define | MN_BACKFACING (1<<3) |
| Indicates that the vertex faces "backwards" in the current viewport. | |
| #define | MN_HIDDEN (1<<4) |
| For MNVerts, MNEdges, and MNFaces, bits 0-7 are used for common characteristics of all components. | |
| #define | MN_CACHEINVALID (1<<5) |
| For MNVerts, MNEdges, and MNFaces, bits 0-7 are used for common characteristics of all components. | |
| #define | MN_INFOREGROUND (1<<7) |
| Tags a face as not renderable but can be hit-test. | |
| #define | MN_WHATEVER (1<<16) |
| #define | MN_LOCAL_SEL (1<<17) |
| Alternate selections (not passed up the pipe). | |
| #define | MN_HITTEST_CULLED (1<<18) |
| Used to indicate culled components (neither selected nor not selected) in window-region hit testing. | |
| #define | MN_USER (1<<24) |
| Any value above this can be used by applications. | |
Vertex Flags | |
| #define | MN_VERT_DONE (1<<8) |
| Set in algorithms that may accidentally revisit the same vertex (MNVertext twice, to keep them from processing it the second time. | |
| #define | MN_VERT_WELDED (1<<9) |
| Used by MNMesh::WeldBorderVerts() | |
| #define | MN_VERT_SUBDIVISION_CORNER (1<<10) |
| Track which vertices are direct "descendants" of the original cage vertices in subdivision. | |
Edge flags | |
| |
| #define | MN_EDGE_INVIS (1<<8) |
| Both faces using this edge consider it invisible. | |
| #define | MN_EDGE_NOCROSS (1<<9) |
| This edge should not be crossed in algorithms like MNMesh::SabinDoo that can mix faces across edges. | |
| #define | MN_EDGE_MAP_SEAM (1<<10) |
| Track which edges are direct descendants of the original cage edges in subdivision. | |
| #define | MN_EDGE_SUBDIVISION_BOUNDARY (1<<11) |
| Track unwanted edges created by Cut, so they might be removed later. | |
| #define | MN_EDGE_CUT_EXTRA (1<<12) |
| Used with MNMesh::CutPrepare() and MNMEsh::CutCleanUp() | |
| #define | MN_EDGE_WAS_PROCESSED (1<<13) |
| This flag is a general-purpose informational one that methods can set to indicate edges that were processed as part of their work, so that callers can act on them if desired. | |
| #define MN_SEL (1<<0) |
For MNVerts, MNEdges, and MNFaces, bits 0-7 are used for common characteristics of all components.
Bits 8-15 are used for component-specific flags. Bits 16-23 are reserved for temporary use in MNMesh algorithms. Bits 24-31 are reserved for MNMath.lib users. Indicates that a component is selected.
| #define MN_DEAD (1<<1) |
Indicates that a component is not used and should be ignored.
Vertices with the MN_DEAD flag are deleted in the next call MNMesh::CollapseDeadVerts().
| #define MN_TARG (1<<2) |
Indicates that a component is targeted.
(the MNMesh methods starting with the words TargetBy.
| #define MN_BACKFACING (1<<3) |
Indicates that the vertex faces "backwards" in the current viewport.
This changes often.
| #define MN_HIDDEN (1<<4) |
For MNVerts, MNEdges, and MNFaces, bits 0-7 are used for common characteristics of all components.
Bits 8-15 are used for component-specific flags. Bits 16-23 are reserved for temporary use in MNMesh algorithms. Bits 24-31 are reserved for MNMath.lib users. Indicates that a component is selected.
| #define MN_CACHEINVALID (1<<5) |
For MNVerts, MNEdges, and MNFaces, bits 0-7 are used for common characteristics of all components.
Bits 8-15 are used for component-specific flags. Bits 16-23 are reserved for temporary use in MNMesh algorithms. Bits 24-31 are reserved for MNMath.lib users. Indicates that a component is selected.
| #define MN_INFOREGROUND (1<<7) |
Tags a face as not renderable but can be hit-test.
1<<6 is skipped because the tri strip uses that as face flag signifying a face to be stripped
| #define MN_WHATEVER (1<<16) |
SDK users should use MN_USER and higher flags.
| #define MN_LOCAL_SEL (1<<17) |
Alternate selections (not passed up the pipe).
| #define MN_HITTEST_CULLED (1<<18) |
Used to indicate culled components (neither selected nor not selected) in window-region hit testing.
| #define MN_USER (1<<24) |
Any value above this can be used by applications.
| #define MN_VERT_DONE (1<<8) |
Set in algorithms that may accidentally revisit the same vertex (MNVertext twice, to keep them from processing it the second time.
| #define MN_VERT_WELDED (1<<9) |
Used by MNMesh::WeldBorderVerts()
| #define MN_VERT_SUBDIVISION_CORNER (1<<10) |
Track which vertices are direct "descendants" of the original cage vertices in subdivision.
| #define MN_EDGE_INVIS (1<<8) |

| #define MN_EDGE_NOCROSS (1<<9) |
This edge should not be crossed in algorithms like MNMesh::SabinDoo that can mix faces across edges.
| #define MN_EDGE_MAP_SEAM (1<<10) |

| #define MN_EDGE_SUBDIVISION_BOUNDARY (1<<11) |
Track unwanted edges created by Cut, so they might be removed later.
| #define MN_EDGE_CUT_EXTRA (1<<12) |
Used with MNMesh::CutPrepare() and MNMEsh::CutCleanUp()
| #define MN_EDGE_WAS_PROCESSED (1<<13) |
This flag is a general-purpose informational one that methods can set to indicate edges that were processed as part of their work, so that callers can act on them if desired.
For example, MNMesh::QuadChamfer will set this flag on any edges that it chamfered and split into two new edges as part of the chamfering process. Other methods may use this flag but the specific meaning is up to the individual method and should be documented along with that method's other usage information. This flag is set by the MNMesh::QuadChamfer() method on any edges that were split into two new edges by the chamfering operation. Used to indicate an edge that was processed by an operation
