Detailed Description

Base class for objects that render information given on the triangle of a Grid.

No shader support here. Use class SurfaceRenderer for more advanced features, including FloatingOrigin.

Todo:

Current implementation does not support caching of multiple grids, e.g. time-dependent data.

Examples

CrystalSurface.cpp, EvolutionSurface.cpp, MonochromeSurface.cpp, PolychromeSurface.cpp, TransparentColoredSurface.cpp, and TransparentSurface.cpp.

Member Function Documentation

computeVertexNormals()

void Wizt::TriangleRenderer::computeVertexNormals ( Fiber::Representation &  myVertices, Fiber::Representation &  mySkeletonAsVertices, VRequest &  Context  )

static

Compute normals in case we don't have any yet.

This is a static member function just for convenience which will create a normal vector field on the vertices under the name TriangularSurface::NormalVectorFieldName .

References Fiber::TriangularSurface::NormalVectorFieldName.

getNormals()

RefPtr< RenderBasin::VertexAttribute > Wizt::TriangleRenderer::getNormals ( const AnemoneCreationContext &  ARC )

static

Query the per-vertex normal vectors for the current triangle fragment as specified via the AnemoneCreationContext and create a vertex attribute from it.

The result can be directly fed to a RenderAnemone:

AnemoneCreationContext&ARC;
     RenderAnemone.insert( getNormals( ARC ) );
