Detailed Description

Base class to render triangular surface using shaders and support for floating origin (i.e., large coordinates).

The shader must support usage of the TranslationVector, which is needed to shift vertices by this amount.

uniform vec3 TranslationVector;
 
void main(void)
{
vec4 trans = vec4(TranslationVector, 0);
vec4 Vertex = gl_Vertex - trans;
 
        gl_Position = gl_ModelViewProjectionMatrix*Vertex;
}

◆ getAnemoneExplorer()

RefPtr< SurfaceRenderer::AnemoneExplorer > Wizt::SurfaceRenderer::getAnemoneExplorer ( VRenderContext & Context ) const

override

The SurfaceAnemoneExplorer is a temporary object that exists while rendering all fragments of a surface.

It is created with the first fragment and destroyed with the last fragment. As such, it defines the scope of a FloatOrigin operation and stores the ModelView matrix which is locally modified during rendering.

Todo:: Use FloatingAnemoneExplorer here.

Create an AnemoneExplorer that lives during the duration of the rendering operation and shifts the coordinate origin according to the FloatOrigin base class specification.
