Meta_ViewShader

A ViewShader represents a shader object, expected to be used by a Meta_ViewFilter.

The inputs to the shader will be set by this nodes children, each of which are expected to be one of the Meta_ShaderABC metanodes (e.g. Meta_ShaderVec3f, Meta_ShaderSampler etc.).

Expected Implementation Details:-

When the SourceCode property changes a search for "#pragma rex Meta_ViewShader with their defined default values, allowing the user to easily configure the shader from the property panel or a script. If these #pragma's are missing in the source the user will have to manually create the child Meta_MaterialParameter nodes and set their values.

Public Types

enum IDX

Property Index.

Idx_SourceCode	string - the source code of the shader. Usually a full GLSL shader but could be just a GLSL function used by a bigger shader.
Idx_Description	string - friendly description of what the shader does, for presenting to the user.
Idx_Target	Target (int)- determines when the shader runs and which buffers it has access to.
Idx_StereoMode	StereoMode (int) - specifies whether the shader applies to mono or stereo views, or both.

enum StereoMode

Values for Idx_StereoMode.

StereoMode_Any	The filter is applied regardless of whether stereo is enabled. (Symbols - C: `"StereoModeAny"`, Lua: `__ViewShader_StereoModeAny`)
StereoMode_MonoOnly	The filter is applied only when rendering in mono. (Symbols - C: `"StereoModeMonoOnly"`, Lua: `__ViewShader_StereoModeMonoOnly`)
StereoMode_StereoOnly	The filter is applied only when rendering in stereo. (Symbols - C: `"StereoModeStereoOnly"`, Lua: `__ViewShader_StereoModeStereoOnly`)

enum Target

Values for Idx_Target.

Target_Viewport	The filter is applied to each viewport immediately after it is drawn, and can use all buffers. (Symbols - C: `"TargetViewport"`, Lua: `__ViewShader_TargetViewport`)
Target_ViewportAfterHDR	The filter is applied to each viewport after the HDR pass (Symbols - C: `"TargetViewportAfterHDR"`, Lua: `__ViewShader_TargetViewportAfterHDR`)
Target_Window	The filter is applied to the entire window after everything including the GUI is drawn, but can use only the colour buffer. (Symbols - C: `"TargetWindow"`, Lua: `__ViewShader_TargetWindow`)
