Walls and floors

I was thinking of a way to do ramps and stairways. After a lot of thought I found a way, and, in the process of adding it, I also made it separate the walls and floors properly, and the walls are now more upright.

My next task will be speeding up the renderer. It is going at about 5-7 FPS at 800x600 at the moment, but I think it can go much faster.

I might also experiment with adding ramps.

Texture alignment

Though you might not see much difference, the changes that I made are important during gameplay. All the stone type boundaries were off by a half cube along all three axes.

I had to modify the terrain shader program extensively, and unfortunately doubled the amount of texture memory required. This means that, to run on computers with 64MB texture memory, the application would need to use lower resolution textures. This is not a problem though, since I believe such graphics cards would not support my shader program anyway.

Again with the rocks

I made the texturing work properly. Just look at this beautiful red sandstone.

Afterward, I added the support for multiple rock types. It is not working nearly as well as this screenshot might lead you to believe. I think I should have stuck with red sandstone, rather than this yellow type. Also, the limestone is looking very blue due to the depth cue. I should fix that.

I am still deciding between using natural stone colors, classifying stone colors, or abstract stone colors.
