Member Function Documentation

virtual void cx::GPUImageLutBufferImpl::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::GPUImageLutBuffer.

Definition at line 272 of file cxGPUImageBuffer.cpp.

virtual void cx::GPUImageLutBufferImpl::bind ( int  textureUnitIndex )

inlinevirtual

If data is changed, send data to GPU.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::GPUImageLutBuffer.
