inlinevirtual

bind the filter kernel texture

Reimplemented in View2DTextureLUTShader.

Definition at line 64 of file View2DShader.h.

bindLutTexture()

virtual void View2DShader::bindLutTexture ( )

inlinevirtual

bind the lut texture to the current texture unit

Reimplemented in View2DTextureLUTShader.
