Maximum number of vertexes

| Hi, Is there a certain maximum of vertexes per surface that Blitz can handle? I created a mazegenerator, which produces a random maze and writes it to a bmp-file (2D top-down view of the maze). After that, the MazeConverter reads that bmp-file and produces the Maze3D structure-code. Then finally Maze3D reads that code and generates a 3D maze, based on that code, in which you can run around (ground and walls are textured). A maze of size 50x50 works fine, but a maze of size 150x150 produces the error "Memory Access Violation" in Maze3D. The 3D model of the maze is only 1 model (one surface). |

| DirectX7 has a vertex limit of ~65.000 i believe.. don't quote me on it though. |
| ||
| I think there's 32000 Triangles limit. (Discussed this recently) Probably 64k Vertices, but you'll be on the save side when you use 32000 only. Simply use multiple surfaces. I think you can have up to 32000 Surfaces. |

| If anyone wants to try the package, you can get it here: http://users.pandora.be/vge/downloads/MazePack.zip Put the executables where you want them (all in one directory, together with the textures). Run MazeGenerator.exe and input the maze-size (square maze), this creates the file Maze.bmp. For a size of 20x20, input "20" (without the ""). Then run MazeConverter.exe, which reads the Maze.bmp file and produces the Maze.dat file. Then run Maze3D.exe. Movement: mouse for looking, arrow-keys for moving forward, backward strafing left and right. To cheat: press Z or S to go up or down in the air (you can see the maze overview that way), gravity must be OFF. Pressing space toggles gravity on/off (it's ON by default). Try a maze of size 50x50 and try to find your way out via Maze3D. Have fun. You can also replace the textures if you want. If you want the source-code for those exe's, let me know and I'll share them. |

| I'm planning to make Maze3D into a FPS and then replace the maze with an actual level. I needed some level to begin with. Now I could add weapons, ammo, health, monsters and other stuff to it. But that's also beyond my current abilities. I haven't created anything that big before (if any game at all). |
| ||
| I've just created a maze of size 60x60, which contains about 49.000 triangles (according to TrisRendered), so the upper limit per surface must be around 65.000 tris, because when I create a maze of size 62x62, it crashes. I don't know how many vertexes there are (I'm not going to count them manually). |
| ||
| As I said some cards crash with >32k Tris. EG mine, a lowcost Radeon 9200se that is a common card in family PCs. |

| I think vertices is the right word when referring to many verticies ^^ |
