Member Function Documentation

virtual void cx::GPUImageLutBuffer::allocate ( )

pure virtual

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.

Implemented in cx::GPUImageLutBufferImpl.

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

pure virtual

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()

Implemented in cx::GPUImageLutBufferImpl.

virtual int cx::GPUImageLutBuffer::getLutSize ( ) const

pure virtual

Size of lut. Used by fragment shader.

Implemented in cx::GPUImageLutBufferImpl.
