Member Function Documentation

◆ GLCacheField()

string VectorViz::VectorSpeckle::GLCacheField ( const RefPtr< ValuePool > & Context ) const

overridevirtual

The name of the field that will be used for caching opengl VBO's at each of this fragments.

This is a temporary workaround. It will NOT work correctly if a VBO depends on multiple fields. The VBO will only change if the GLCacheField changes (ie., its fragments).

There will be ONE VBO per fragment of this GLCacheField.

Per default, this will be the FragmentSelectionField().

If a rendering method implements a vector field visualization of Grid that does not change, then this function would refer to the name of that vector field. However, if the coordinates changes but not the vector field, it will still display the same. This needs to be reworked.

Reimplemented from Wizt::FragmentPainter.

◆ newState()

RefPtr< VObject::State > VectorViz::VectorSpeckle::newState ( ) const

inlineoverridevirtual

Reimplemented from Wizt::VStateCreatorBase.

◆ setShaderVariables()

void VectorViz::VectorSpeckle::setShaderVariables	(	VGLRenderContext &	Context,
		const RefPtr< GLProgram > &	ShaderProgram ) const

overridevirtual

Virtual function to set variables in the shader program, such as parameters from the Vish inputs.

Typical code might just assign slots to uniform variables:

struct  MySplatter : SplatRenderObject
{
     TypedSlot<double>   Value;
 
     MySplatter(...)
     : SplatRenderObject(...)
     , Value(this, "value", 0.23)
     {}
 
     string vertex_shader(VRenderContext&Context) const override
     {
        return "uniform float value; ....";
     }
 
        void setShaderVariables(VRenderContext&Context, const RefPtr<Program>&ShaderProgram) const override
     {
        Value << Context > ShaderProgram;
     }
};

Note that the name of the slot must be equal to the name of the uniform variable in the shader program for this to work. If the names don't match, then an OpenGL error exception will be thrown.

Reimplemented from Wizt::SplatRenderObject.
