template<typename BaseVecT>
class RaycastingTexturizer : public lvr2::Texturizer<BaseVecT>

This class implements the Texturizer interface. It uses Raycasting for the calculation of the texture pixels.

Template Parameters:

BaseVecT –

Public Functions

RaycastingTexturizer() = delete
RaycastingTexturizer(float texelMinSize, int texMinClusterSize, int texMaxClusterSize, const BaseMesh<BaseVector<float>> &geometry, const ClusterBiMap<FaceHandle> &clusters, const ScanProjectPtr project)

Construct a new Ray Casting Texturizer object.

Parameters:

  • texelSize – The size of one texture pixel, relative to the coordinate system of the point cloud

  • texMinClusterSize – The minimum number of faces a cluster needs to be texturized

  • texMaxClusterSize – The maximum number of faces a cluster needs to be texturized

virtual TextureHandle generateTexture(int index, const PointsetSurface<BaseVecT> &surface, const BoundingRectangle<typename BaseVecT::CoordType> &boundingRect, ClusterHandle cluster) override

Generates a texture for a given bounding rectangle.

Create a grid, based on given information (texel size, bounding rectangle). For each cell in the grid (which represents a texel), cast a ray from the camera to the texel in 3D space to check for visibility. If the texel is visible calculate the texel color based on the RGB image data.

Parameters:

  • index – The index the texture will get

  • surface – The point cloud

  • boundingRect – The bounding rectangle of the cluster

Returns:

Texture handle of the generated texture
