Implement a post-processing Gaussian blur render pass.
Blur the image renderered by its delegate. Blurring uses a Gaussian low-pass filter with a 5x5 kernel.
This pass expects an initialized depth buffer and color buffer. Initialized buffers means they have been cleared with farest z-value and background color/gradient/transparent color. An opaque pass may have been performed right after the initialization.
The delegate is used once.
Its delegate is usually set to a vtkCameraPass or to a post-processing pass.
This pass requires a OpenGL context that supports texture objects (TO), framebuffer objects (FBO) and GLSL. If not, it will emit an error message and will render its delegate and return.
- Implementation:
- As the filter is separable, it first blurs the image horizontally and then vertically. This reduces the number of texture sampling to 5 per pass. In addition, as texture sampling can already blend texel values in linear mode, by adjusting the texture coordinate accordingly, only 3 texture sampling are actually necessary.
