C# Class QuadVideo.XYAxesPointMesh

This object uses a set of quads to represent a mesh that is in the XY plane. A size parameter sets the model coordinate boundaries of the mesh The Resolution determines how many quads are constructed along each axis. This class clearly separates the creation of vertices, indices, and texture coodinates for the sake of clarity. It may not be the most efficient manner, but is probably the easiest to understand, modiy, extend, and maintain. This is not the most optimal representation of a mesh of quads. First, the individual vertices are duplicated rather than shared. This is to allow setting of individual normal vectors, and texture coordinates per vertex. Also, instead of using quad strips, each individual quad is drawn as a separate object. Again, this is for full control of drawing. One scenario might be that each individual quad is drawn and some shader parameters are set before the drawing occurs. This might allow a shader to convey information to the quad such as which position it is in relative to the resolution of the entire mesh.

Public Methods

Method Description
CreateVertices ( ) : void
Render ( GraphicsInterface GI ) : void

This override is called by whomever is controlling the rendering process. We call the base Render method as it will automatically use the vertices, indices, and texture coordinates to draw the quads.
XYAxesPointMesh ( GraphicsInterface gi, Vector3D boundary, Resolution res, GLTexture texture ) : System

To construct a mesh, we need to know the size and resolution. We also set the texture as a convenience.
XYAxesPointMesh ( Vector3D boundary, Resolution res ) : System

To construct a mesh, we need to know the size and resolution. We also set the texture as a convenience.

Private Methods

Method Description
CreateIndices ( ) : void
CreateMesh ( ) : void

Do the work of creating the mesh vertices and indices. The general routine is to create a mesh in the x-y plane, using the appropriate width and height.
CreateTextureCoords ( ) : void
