As an experiment, I’d like to load data from a GeoTiff texture and pass it through to a shader. The goal is to generate colors, using the unconstrained values in the geotiff. This experiment is part of my larger exploration into the world of Cesium. I’m currently using Resium in a Create-React-App.
I’ve got a primitive describing a rectangle, to which I’ve assigned a new materialappearance. My shader is in the source property for the material assigned to the material appearance, not in fragmentShaderSource of the appearance.
I’d like to pass a new WebGLTexture with GL.R32F format as a uniform into the material. I’ve grabbed the WebGLContext from the viewer, and am creating a new texture succesfully.
However, when I try to assign my texture to a uniform in the material, I get a Fabric Error: ‘Uniform is invalid type’
Does anyone know what I’m doing wrong? How can I my desired effect?
