Shader (vuo.shader)

Nodes for creating graphics shaders to be used to paint 3D objects.

A shader controls how a 3D object is rendered, such as its color, texture, and lighting. Shaders are an efficient way to add effects to 3D objects because they take advantage of graphics card acceleration.

You can connect these nodes to nodes from the vuo.scene node set to draw 3D scenes.

Example compositions:

• Compare Color and Edge Shaders: Renders 2 copies of a 3D object side-by-side with different shaders.
• Meet the Ghost of Einstein: Demonstrates using the Make Edge Shader node for a ghostly effect.
• Move Light across Tile: Renders a 3D object with surface details, and moves a light across it to show the details in relief.
• Show Sphere through Warped Plastic: Renders a sphere distorted through a sheet of warped plastic.
• Spin Wireframe Sphere: Displays a rotating wireframe sphere.

Nodes:

• Make Edge Shader (vuo.shader.make.edge.color): Creates a graphics shader that paints a 3D object opaque near the edges and transparent in the center (or vice versa).
• Make Frosted Glass Shader (vuo.shader.make.frost): Creates a graphics shader that can paint a 3D object like frosted glass.
• Make Image Details Shader (vuo.shader.make.image.details): Creates a graphics shader that can paint surface details on a 3D object.
• Make Lit Color Shader (vuo.shader.make.color): Creates a graphics shader that can paint a 3D object with a solid color.
• Make Lit Image Shader (vuo.shader.make.image): Creates a graphics shader that can paint an image on a 3D object.
• Make Oval Shader (vuo.shader.make.oval): Creates a graphics shader that paints a 3D object with an oval and a halo.
• Make Unlit Color Shader (vuo.shader.make.color.unlit): Creates a graphics shader that can paint a 3D object with a solid color.
• Make Unlit Image Shader (vuo.shader.make.image.unlit): Creates a graphics shader that can paint an image on a 3D object.
• Make Vertex Attribute Shader (vuo.shader.make.normal): Creates a graphics shader that can paint colors on a 3D object representing its vertex attributes.
• Make Wireframe Shader (vuo.shader.make.wireframe): Creates a graphics shader that can paint the outline of a 3D object.
