texCoord1	This is not interleaved with the other data in GPU memory.
boneIndices,boneWeights	These are only interleaved with each other in GPU memory
vertexColors	This is not interleaved with the other data in GPU memory.

hasPrevPosition()

bool G3D::CPUVertexArray::hasPrevPosition ( ) const

inline

True if prevPosition is nonempty.

It is ambiguous if an empty vertex array has a prevPosition array.

transformAndAppend() [2/2]

void G3D::CPUVertexArray::transformAndAppend	(	const CPUVertexArray &	otherArray,
		const CoordinateFrame &	cframe,
		const CoordinateFrame &	prevCFrame
	)

Transform otherArray.vertex.position by cframe and append to vertex.position.

Transform otherArray.vertex.position by prevCFrame and append to prevPosition. Assumes that otherArray does not contain a prevPosition array of its own.

Member Data Documentation

boneIndices

Array<Vector4int32> G3D::CPUVertexArray::boneIndices

4 indices indicating the bones that affect animation for the vertex

Referenced by clear(), and G3D::ArticulatedModel::Geometry::hasBones().

boneWeights

Array<Vector4> G3D::CPUVertexArray::boneWeights

4 floats indicating the weighting for the 4 bones that affect animation for the vertex

Referenced by clear().

hasBones

bool G3D::CPUVertexArray::hasBones

True if boneIndices and boneWeights contain valid data.

Referenced by clear().

hasTangent

bool G3D::CPUVertexArray::hasTangent

True if tangent contains valid data.

Referenced by clear().

hasTexCoord0

bool G3D::CPUVertexArray::hasTexCoord0

True if texCoord0 contains valid data.

Referenced by clear(), and hasTexCoord().

hasTexCoord1

bool G3D::CPUVertexArray::hasTexCoord1

True if texCoord1 contains valid data.

Referenced by clear(), and hasTexCoord().

hasVertexColors

bool G3D::CPUVertexArray::hasVertexColors

True if vertexColors contains valid data.

Referenced by clear().

prevPosition

Array<Point3> G3D::CPUVertexArray::prevPosition

The position of the vertex in the previous frame, in the same coordinate system as vertex.position.

This is stored outside of the CPUVertexArray::vertex array because it is not used by most models.

Referenced by clear(), and hasPrevPosition().

texCoord1

Array<Point2unorm16> G3D::CPUVertexArray::texCoord1

A second texture coordinate (which is not necessarily stored in texture coordinate attribute 1 on a GPU).

This must be on [0,1]. Typically used for light map coordinates.

This is stored outside of the CPUVertexArray::vertex array because it is not used by most models.

Referenced by clear().

vertex

Array<Vertex> G3D::CPUVertexArray::vertex

Referenced by clear(), G3D::Tri::position(), size(), and G3D::Tri::vertex().

vertexColors

Array<Color4> G3D::CPUVertexArray::vertexColors

Vertex Colors.
