pixelate texture for CreateGroundFromHeightMap?


Recommended Posts

I know its a nice feature that the texture in the height map does smear out the pixels of the underlying texture image. But I just happen to need to see the pixel borders very clearly on the ground. is there a way to set the material to do this?

I am using the demo for CreateGroundFromHeightMap as base


Sorry if this is trivial, trying to learn....

one other trick I use, is to change the uScale and vScale values of the texture.

	var ground = BABYLON.Mesh.CreateGroundFromHeightMap("ground", "textures/heightMap.png", 100, 100, 100, 0, 10, scene, false);
	var groundMaterial = new BABYLON.StandardMaterial("ground", scene);
	groundMaterial.diffuseTexture = new BABYLON.Texture("textures/ground.jpg", scene);
	groundMaterial.diffuseTexture.uScale = 6;
	groundMaterial.diffuseTexture.vScale = 6;

Try http://www.babylonjs-playground.com/#10JKYM#3, change the uScale and vScale values to 1. You'll notice immediate pixellation as the texture is being stretched thin.

Thank you all for your answers. I am not getting anywhere near what I need though. I need the ground to show the exact colour of that texture pixel (texture has same size as height map). I added the following which I found from another thread:

ground.coordinatesMode = BABYLON.Texture.PLANAR_MODE;


but that did not help either: http://www.babylonjs-playground.com/#10JKYM#6


It seems like the texture-image has been resampled? Is it possible to turn this off?


I need the ground to look something like this at close range (i.e. sharp edges of the pixels):





I would greatly appreciate any further insights from you kind people :-)


Many thanks
