SBSurface

SBSurface#

This class describes a renderable surface that stores the triangle geometry of a mesh.

Surfaces are typically obtained from a mesh, but they can also be constructed explicitly from geometry arrays when building custom visual data in Python.

This class describes a surface.

Constructs a surface from explicit geometry arrays.

Array sizes must match: - indexData: 3 * numberOfTriangles - positionData: 3 * numberOfPositions - normalData: 3 * numberOfPositions - colorData: 4 * numberOfPositions - flagData: numberOfPositions - nodeIndexData: numberOfPositions - textureCoordinateData: 2 * numberOfPositions

getColorData(self: samson.SBSurface) → list[float]#: Returns the color data; size: 4 * numberOfPositions

getDiffuseTexture(self: samson.SBSurface) → SBMVisualModelTexture#: Returns the diffuse texture

getFlagData(self: samson.SBSurface) → list[int]#: Returns the flag data; size: numberOfPositions

getIndexData(self: samson.SBSurface) → list[int]#: Returns the index data; size: 3 * numberOfTriangles

getNodeIndexData(self: samson.SBSurface) → list[int]#: Returns the node index data; size: numberOfPositions

getNormalData(self: samson.SBSurface) → list[float]#: Returns the normal data; size: 3 * numberOfPositions

getPositionData(self: samson.SBSurface) → list[float]#: Returns the position data; size: 3 * numberOfPositions

getTextureCoordinateData(self: samson.SBSurface) → list[float]#: Returns the texture coordinate data; size: 2 * numberOfPositions

setColorData(self: samson.SBSurface, data: list[float]) → None#: Sets the color data; size: 4 * numberOfPositions

setDiffuseTexture(self: samson.SBSurface, texture: SBMVisualModelTexture) → None#: Sets the diffuse texture

setFlagData(self: samson.SBSurface, data: list[int]) → None#: Sets the flag data; size: numberOfPositions

setIndexData(self: samson.SBSurface, data: list[int]) → None#: Sets the index data; size: 3 * numberOfTriangles

setNodeIndexData(self: samson.SBSurface, data: list[int]) → None#: Sets the node index data; size: numberOfPositions

setNormalData(self: samson.SBSurface, data: list[float]) → None#: Sets the normal data; size: 3 * numberOfPositions

setPositionData(self: samson.SBSurface, data: list[float]) → None#: Sets the position data; size: 3 * numberOfPositions

setTextureCoordinateData(self: samson.SBSurface, data: list[float]) → None#: Sets the texture coordinate data; size: 2 * numberOfPositions

property numberOfPositions#: Number of vertex positions in the surface.

property numberOfTriangles#: Number of triangles in the surface.
