Hi all, I am trying to create a textured object made of several geometries using different textures but the same vertex array, and I failed to apply textures.
Here is what I do : the object is an extruded building. I have the footprint of the building - a polygon made of n cartographic points ( X, Y ) -, its height, a texture for the roof, and one texture for each wall. I create a Vec3Array made of the coordinates of the roof ( x, y, height ), followed by the coordinates of the ground footprint ( x, Y, 0 ), the size of this array is 2 * n. First, I create the roof, a Geometry with a POLYGON PrimitiveSet using the first n points of the array. I apply the texture to the roof using a n sized texture coordinates array. This works well. Then, for each wall, I create a Geometry including a TRIANGLES PrimitiveSet. This one is made of two triangles using for points of the Vec3Array ( the two triangles of the first wall use points at indices 0, 1, n and n+1 ). This works fine. The problem is when I want to apply textures to the wall. I specify a texture coordinates for each point and the texture is not applied properly. I have tried to specify texture coordinates indices - inside the Vec3Array - using setTexCoordIndixes, but this doesn't work. Is it possible to share the coordinates array between different textured geometries and use apply a different texture to each geometry ( roof and walls ) using texture coordinates and texture coordinates indices ? Any hints or comments ?
