Member Function Documentation

virtual void cx::GPUImageDataBufferImpl::allocate ( )
inlinevirtual

Allocate resources for the lookup table and the volume on the GPU. Prerequisite: SetImage and SetcolorTable has been called.

Call this from inside a PrepareForRendering() methods in vtk.

Implements cx::GPUImageDataBuffer.

Definition at line 113 of file cxGPUImageBuffer.cpp.

virtual void cx::GPUImageDataBufferImpl::bind ( int  textureUnitIndex)
inlinevirtual

Activate and bind the volume and lut buffers inside the texture units GL_TEXTURE<2X> and GL_TEXTURE<2X+1>. Use during RenderInternal()

Implements cx::GPUImageDataBuffer.

inline

Definition at line 224 of file cxGPUImageBuffer.cpp.

virtual int cx::GPUImageDataBufferImpl::getMemorySize ( )
inlinevirtual

Implements cx::GPUImageDataBuffer.

Definition at line 90 of file cxGPUImageBuffer.cpp.

virtual unsigned int cx::GPUImageDataBufferImpl::getTextureUid ( ) const
inlinevirtual

Return the texture uid for this object, as generated by glGenTextures().

Prerequisite: allocate() has been called.

Implements cx::GPUImageDataBuffer.
