Techniques to make shaders more efficient
What is a cheap shader? When you're asked the question for the first time, it might be a little tough to answer since many elements go into making a more efficient shader. It could be the amount of memory that's used up by your variables. It could be the number of textures the shader is using. It could also be that our shader is working fine, but we can produce the same visual effect with half the amount of data by reducing the amount of code we are using or the data we are creating. We are going to explore a few of these techniques in this recipe. We will show how they can be combined to make your shader fast and efficient while still producing the high-quality visuals everyone expects from games today, whether on a mobile or PC.
Getting ready
To get started, we need to gather a few resources. So, let's perform the following tasks:
- Create a new scene and fill it with a simple sphere object and a single directional...
