Map

[Jonotron]

Hey, glad you got a forum up!  I would like to know how you'd make a terrain like this one:

except, just making a flat map, not a height map.

Not sure what you mean by 'flat map'. Can you clarify?

[chadmv]

Maybe he means like a minimap or radar.

Sorry for the confusion, it was late when I wrote that.  I mean ground to for an object to move on.

Well, you could go about this a lot of ways. If you wanted an entirely flat surface to move things on (as in a small physics engine test, or maybe a simple track racing game) you could simply use a single quad that has a texture scaled to full (or repeated depending on your needs) and just tell the objects in the game that the ground plane is at that object's height.

You could also do a much larger level with multiple quads so that you could cull them when they are outside the frustum (although with single quads, culling would be entirely unneccessary). Chad (chadmv) has a culling tutorial over at c-unit that works with his engine setup.

Thanks, I'm just trying to test out a simple terrain(ground) class.  I think making multiple quads would be best.  I've looked at the C-Unit tutorials and I like them, but it doesn't explain the framework enough, so I get lost after a while.  For creating a grid of quads, would I use VertexGroup? like this:

Code:

            verts = new CustomVertex.PositionTextured[4];
            /*
             * gotta edit the next few lines
             */
            verts[0] = new CustomVertex.PositionTextured(new Vector3(-1, -1, 1), 0, 0);
            verts[1] = new CustomVertex.PositionTextured(new Vector3(1, -1, 1), 1, 0);
            verts[2] = new CustomVertex.PositionTextured(new Vector3(-1, -1, -1), 0, 1);
            verts[3] = new CustomVertex.PositionTextured(new Vector3(1, -1, -1), 1, 1);
            ground = new VertexGroup(verts, inds, texture, myDevice);

If so, how do I edit the "new Vector3(#, #, #)" part to specify how many quads per x axis and per z axis?
