Detailed Description

Generates a PerPixelMap from an ITKMesh and a UVMap.

Rasters a UVMap and embeds the raster with 2D-to-3D lookup information. Each pixel in the PPM stores a vector of six double-precision floats which correspond to the 3D position and normal vector associated with that pixel: {x, y, z, nx, ny, nz}

This class uses raytracing functionality provided by the bvh library.

Member Enumeration Documentation

Shading

enum class volcart::texturing::PPMGenerator::Shading

strong

Pixel normal shading method.

Enumerator
Flat	Each pixel inherits the face's normal.
Smooth	Each pixel's normal is a linear interpolation of the face's vertex normals. This is similar to Phong shading.

Definition at line 33 of file PPMGenerator.hpp.
