shadowsExample

Learning Objectives

This example demonstrates how to use multiple lights, shadows, materials and meshes. The lights move around the scene and slowly change color.

You will learn how to..

• setup a point and spot light with shadows
• configure materials
• load a mesh from disk
• use a function to render a scene multiple times in one draw call
• draw the light shadow frustums

Pay attention to..

• ofShadow::enableAllShadows()
• ofShadow::setAllShadowNormalBias(-4.f);
• ofShadow::setAllShadowTypes(shadowType);
• the light for loop in the draw function to render the scene into the shadow depth maps, ie if( light->shouldRenderShadowDepthPass() ) {

Expected Behavior

When launching this app, you should see the OF logo, two cubes, a sphere and a point light going through the O.

Instructions for use:

• Press spacebar to enable and disable shadows.
• Press f to toggle drawing frustums
• Press right to change the shadow type between hard and softer shadows
• Press up and down to increase and decrease the sample radius, the larger the sample, the more blurry ( does not apply to hard shadows ).
