Are Animated Height Maps Possible?

Hi,

I know how to create height maps in Babylon using code like this:

            // Ground EDIT to suit color and monochrome images
			var image = 'color.png';
            var heightmap = 'mono.png';                
            var groundMaterial = new BABYLON.StandardMaterial("ground", scene);
            groundMaterial.diffuseTexture = new BABYLON.Texture(image, scene);
			groundMaterial.specularColor = new BABYLON.Color3(0, 0, 0);				
            var ground = BABYLON.Mesh.CreateGroundFromHeightMap("ground", heightmap, 402, 204, 200, 40, 0, scene, false);
            ground.material = groundMaterial;

I want to create dynamic height maps whose topography is controlled by a video file. However, if I change the PNG files above to AVI videos the model does not load.

Is it possible to create animated height maps from video files?

thx in advance

Dave

Yes, it’s possible, but you’ll need some custom shaders.

Thanks for the clue. It looks like a baked vertex animation texture will do the job.
