This project uses C# (and winforms) to present a basic approach to the z-buffer rendering algorithm (wikipedia) for objects in 3D space.

The application allows stacking of various objects

And moving objects around the scene

The winforms main window isDisplay.cs. Cubes are added and defined ininitializeCubes(). A cube is added in the following way:

Cubec3=Cube.UnitCube(1337);// Create a unit cube with color seed (int)c3.Rescale(2,5,15);// Rescale on x, y and z dimensionsc3.Translate(newVector3D(0,-15,0));// Set offsetc3.RotateAroundOrigin(-Math.PI/3,Math.PI/8,-Math.PI/2);// Rotate with respect to/anchored in Origin point (0, 0, 0)cubes.Add(c3);// Add the cube to list of cubes

Drawing.cs is the master class used for z-buffer rendering andZBuffer.cs is used to store z-indicies of the projected points. Points are drawn to a bitmap with an extension method which directly writes to memory for better performance.

The below set of combinations of keys and functional keys (shift/ctrl) are used to control the simulation.

Where applicable (in Note column), keys may be modified with the Ctrl key to increase the value of action (ie.<selected key> + Ctrl will perfrom the appropriate action with higher value - translation by 10 points instead of 2, etc.)

Objects are always moved with respect to their local axis.
