One option is to use a texture that is larger than you need and just crop it using texture coordinates. Remember that your texture does not need to exactly fit your shape, but you can let the texture coordinates go from 0 to .75 for example.
However in this case you would need a 1024x1024 texture, which is rather large and will probably not perform well on most video cards. A general rule of thumb is to keep the texture size to 256x256, but if performance isn't a big concern right now, give it a try. -mike -----Original Message----- From: Discussion list for Java 3D API [mailto:[EMAIL PROTECTED] On Behalf Of Fraser MacLeod Sent: Wednesday, September 29, 2004 6:31 AM To: [EMAIL PROTECTED] Subject: [JAVA3D] Applying texture to terrain Hi; I am using a DEM file to generate a virtual terrain (650x1000 grid cells in the terrain). Using this I am computing those areas of the terrain visible from a point and storing this as an array (1=visible, 0=non visible for each grid cell). I would like to overlay the visiblility information as a texture onto the terrain - the effect that I want is one where red tinged cells are visible, and dark tinged cells are non-visible. I am struggling to find a way of doing this given that the terrain/visibility arrays are not powers of 2. Is there something like an ELevationGridGenerator for textures? Any suggestions more than welcome.
