C# Class renderers.Rasterizer

Represents a software rasterizer that can render BFSOctrees. It supports phong shading and can render models consisting of 200k - 750k voxels in realtime on multi-core systems. The rasterizer is used for testing purposes. If a voxel covers many pixels, the rasterizer doesn't color all of them for performance reasons. It only colors the pixel nearest to the voxel center. This information is encoded in textures which are sent to the GPU, which then fills all pixels of the image (via shaders).

Public Methods

Method	Description
Rasterizer ( int horRes, int vertRes )	Creates a new Rasterizer.
draw ( GraphicsDevice device ) : void	Called by Game1, draws the final image. This happens independent of a call to Rasterizer.render. If this method is called without calling Rasterizer.render prior to it, an empty screen appears.
loadContent ( GraphicsDevice device, ContentManager cm ) : void	Called by Game1. Initializes textures, buffers, etc.
render ( Object3D object3D, Camera fromPerspective, int threadIndex ) : void	Renders the sparse voxel octree stored in obj. - Viewing frustum culling - Level of detail

Private Methods

Method	Description
traverse ( Object3D obj, uint offset, int x, int y, int z, Matrix projection, Matrix worldView, Matrix worldViewProjection, byte level, float halfDim, int threadIndex, Vector3 octreeMin ) : void	Traverses all octree nodes and draws them. Used by Rasterizer.render.

Method Details

horRes	int	Horizontal screen resolution.
vertRes	int	Vertixal screen resolution.

draw() public method

Called by Game1, draws the final image. This happens independent of a call to Rasterizer.render. If this method is called without calling Rasterizer.render prior to it, an empty screen appears.
