Add the Material to the Mesh. I would have expected them to be equivalent. We’ll create the material without passing any parameters into the constructor, so we’ll get a default white material. // Sample the correct color from the generated texture // // Notice how we now apply a slight 0.005 offset to our UVs when // looking up the correct texture color vec4 inputColor = texture2D(sampler, v_uv + vec2(0.005)); // Set the correct color of each pixel that makes up the plane // // We fade out the color from the previous step to 97.5% of . Even though three.js might look complex at first, it would actually take even more code to . We’ll add some lights to our scene in 1.4: Physically Based Rendering and Lighting. See the three.js documentation for detailed information on the components that make up a scene in three.js. Next, let's start by filling in the script tag.
