Labs Octahedron Lens

This is a CVEX based Lens Shader used to generate Impostors.

This is a CVEX based Lens Shader used to generate Impostors inside the Impostor Texture ROP. This tool by itself is exposed because of its educational worth. Please note that the lens shader code is found in the “Code” section of the HDA.

Parameters

xy_size

This specifies the number of impostor renders there are generated for both X and Y axis. (Ex 8 would result in 64 angles)

camera_width

Sets the camera width of the lens shader. A larger camera width allows for larger objects to be rendered.

camera_zoom

Controls the zoom of the lens. Smaller values means more zoomed in.

imposter_mode

Sets the type of octahedral impostor that needs to be rendered.
