Detailed Description

Base class for render object that draw a splat for each vertex of a Grid object.

Subclasses may define the way how such splats are drawn, and parameterize them based on the given input fields.

Todo:: Derive from class Programmable instead of doing same stuff here manually. Code is currently messy with VGLRenderContext and VRenderContext mixed. Also, need to replace GL_POINT_SPRITE with using billboards generated by a Geometry shader since point sprites are deprecated in OpenGL 3.

Constructor & Destructor Documentation

◆ SplatRenderObject()

Wizt::SplatRenderObject::SplatRenderObject	(	const string &	name,
		int	p,
		const RefPtr< VCreationPreferences > &	VP,
		double	SizeScale = `150.0`,
		int	AnimationVisibility = `5`
	)

Constructor.

Parameters

AnimationVisibility The expert level of the AnimationSpeed parameter. It sets an uniform float "fractime" in the shader program to cycle between 0.0 and 1.0 in a certain speed. If the AnimationSpeed is larger than 0.0, then the rendering will auto-update.

		const RefPtr< MemBase > &	FieldCoordinates,
		const RefPtr< FragmentSelector > &	FS
	)		const

overridevirtual

Render function: create a renderer object.

Overrides virtual function from FragmentPainter .

Reimplemented from Wizt::FragmentPainter.

◆ FragmentShaderPrefix()

string Wizt::SplatRenderObject::FragmentShaderPrefix ( VRenderContext & ) const

virtual

Predefined way to set the name of a render object.

Todo:: : This function should be removed by using the Programmable basis class. It was added here to emulate similar behaviour of the newer infrastructure.

Referenced by renderGL().

◆ help()

string Wizt::SplatRenderObject::help ( HelpType HT = HTMLText ) const

overridevirtual

Reimplemented from Wizt::VObject.

◆ renderGL()

bool Wizt::SplatRenderObject::renderGL ( VGLRenderContext & Context ) const

overridevirtual

Creates an OpenGL Shader, and finally calls renderFragments().

If a file Name().vert or Name().frag exists, then the GLGS source code within these files will be loaded instead of the intrinsic code.

Implements Wizt::VGLRenderObject.

References MemCore::FileRead(), floor(), FragmentShaderPrefix(), Wizt::VStateCreatorBase::getState(), Fiber::ElementIterator< T >::length, std::multimap< string, RefPtr< VertexField > >::max_size(), Wizt::VStateCreatorBase::myState(), MemCore::MutableName::Name(), Wizt::FragmentPainter::renderFragments(), setPointAttenuation(), and setShaderVariables().

◆ setPointAttenuation()

string Wizt::SplatRenderObject::setPointAttenuation ( const string & ModifySizeFunction = DefaultModifySizeFunction )

static

A vertex shader fragment defining a function that will set the gl_PointSize to some value suitable for splats that get smaller in distance.

Also it will let them fade out once too small. Add this code to the prefix of some vertex shader.

void main(void)
{
        gl_FrontColor.rgb = vec3(0.5,0.5,0.3);
"       gl_Position = gl_ProjectionMatrix * gl_ModelViewMatrix * gl_Vertex;
 
        gl_FrontColor.a = setPointAttenuation();
 }

This function will return the following GLGS code:

uniform float size;
 
float setPointAttenuation()
{
vec4    eyeCoord = gl_ModelViewMatrix * gl_Vertex;
float   dist = distance(eyeCoord, vec4(0.0, 0.0, 0.0, 1.0));
float   att = 1.0/dist;
float   diameter = clamp(size* att, 0.0,100.0);
 
float   fadeThreshold = 1.0;
float   fadePower = 1.5;
        gl_PointSize = max(diameter, fadeThreshold);
float   fade = min(diameter, fadeThreshold)/fadeThreshold;
        return pow(fade, fadePower)
}

Alternatively, the size can also be an attribute, in which case the GLSL code will look like this:

attribute float size;

◆ setRendererParameters()

void Wizt::SplatRenderObject::setRendererParameters	(	VGLRenderContext &	Context,
		const RefPtr< VBO::Renderer > &	theRenderer,
		const RefPtr< CreativeArrayBase > &	VertexCoordinates,
		const RefPtr< GLProgram > &	theShaderProgram
	)		const

override

Update a renderer object, in case the fragment selector is newer.

Render function: set parameters in the renderer that don't need re-creation of the VBO

References Wizt::SplatRenderObject::Renderer::accumulative, Wizt::SplatRenderObject::Renderer::accumulative_absorption, Wizt::SplatRenderObject::Renderer::alphaclamped, Wizt::SplatRenderObject::Renderer::alphaToCoverage, and Wizt::SplatRenderObject::Renderer::depthsorted.

◆ setShaderVariables()

void Wizt::SplatRenderObject::setShaderVariables	(	VGLRenderContext &	Context,
		const RefPtr< GLProgram > &	ShaderProgram
	)		const

virtual

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.

◆ default_fragment_shader

const char Wizt::SplatRenderObject::default_fragment_shader

static

Initial value:

=
"uniform sampler2D PSFTexture;\n"
"void main (void)\n"
"{\n"
"vec4   psf  = texture2D( PSFTexture, gl_TexCoord[0].st);\n"
 
"       gl_FragColor.rgb = (psf*gl_Color).rgb;\n"
"       gl_FragColor.a = max(psf.r, max(psf.g, psf.b))*gl_Color.a;\n"
 
"}\n"

Default fragment shader code, must derive from to get this 2D texture.

uniform sampler2D PSFTexture;
void main (void)
{
vec4    psf  = texture2D( PSFTexture, gl_TexCoord[0].st);
gl_FragColor = psf*gl_Color;

◆ default_vertex_shader

const char Wizt::SplatRenderObject::default_vertex_shader

static

Initial value:

=
"uniform vec4 SplatColor;\n"
 
"#ifndef        CONSIDER_TRANSLATION_VECTOR\n"
"uniform vec3 TranslationVector;\n"
"#endif\n"
 
"void main(void)\n"
"{\n"
"       gl_FrontColor = SplatColor;\n"
 
"       gl_Position = gl_ProjectionMatrix * gl_ModelViewMatrix * (gl_Vertex - vec4(TranslationVector, 0) );\n"
 
"       gl_FrontColor.a *= setPointAttenuation();\n"
" }\n"

       Default vertex shader code that sets point size and transparency
       attenuation for very small points. To make use of this functionality,
       the code returned by setPointAttenuation() must be included in the
       code provided by an implementation of this function, and the
       setPointAttenuation() function needs to be called in the vertex shader.
       Its return value is a transparency factor that is supposed to be used
       to attenuate the alpha value of the given colors. The default main function
       as returned by the vertex_shader function is

void main(void)
{
        gl_FrontColor.rgb = vec3(0.5,0.5,0.3);
        gl_Position = ftransform();
        gl_FrontColor.a = setPointAttenuation();
}
