The Shader Development Studio3.5 Shader animationThe Shader Development Studio also supports shader animation. This can be used to see how ashader effect changes over time. This section describes how to set up a shader for animation andhow to animate the shader.3.5.1 Setting up a shader to use animationA shader is animated using a key framing method. Values are set for the initial frame and finalframe, the Shader Development Studio then interpolates the values between these two frames tocreate the animation effect.The Environment Mapping shader demo provided in the content directory is set up to useanimation. To view how animation has been setup for this shader:1. Open the project that you created containing the Example content provided with theShader Development Studio software. See Importing existing Shader effects andconfigurations on page 3-14.2. In the Shader Control view, select ExampleContent → Demo 07 - EnvironmentMapping.The Shader Preview is updated to show a custom geometry called ARM, with environmentmapping applied. See Figure 3-23:Figure 3-23 ARM geometry3. The Shader Control view and the Shader Uniforms view set up the key framingparameters for the shader animation.In the Camera control group box in the Shader Control view, values are set for:• camera position for the first frame, this is also the camera position used to rendersingle-frame shaders• camera position of the last frame and the number of frames to render.
