Lecture Rendering pipeline, shaders and effects 1Elias Holmlid

 First part:  The rendering pipeline  Effects & shaders overview  XNA, HLSL & Effects  Shader authoring tools  Particle Systems  Second part  Effect, texturing and particle system example Elias Holmlid2

 Rasterization  Taking vertex positions from the vertex shader and transforming them into pixels. Elias Holmlid4

 Transform and shading of geometry  Particles: motion + shading  Intermediate buffers (textures)  Post processing Elias Holmlid5

 Texture Elias Holmlid6

 Texture +  Directional light Elias Holmlid7

 Texture +  Directional light +  Spotlight Elias Holmlid8

 Texture +  Directional light +  Spotlight +  Normal map Elias Holmlid9

Elias Holmlid12  Example: Heat texture

Elias Holmlid13  Example: Soft shadows

 C-like syntax  No object orientation  Functions can be used  By using include-files, functions and datatypes can be reused Elias Holmlid15

 Vertex shader  Used to transform vertices ▪ Solids deforming ▪ Skeletal animation ▪ Particle motion Elias Holmlid18

 Pixel shader  Manipulates pixel color and optionally the pixel depth.  Examples: ▪ Lighting ▪ Contrast ▪ Blur Elias Holmlid19

 Easy to work with in XNA  Represented by the class Effect  Effect effect;  effect.Load (”/effects/lightEffect”);  You can then set the attributes of the effect  effect.Parameters[”lightPosition”].SetValue()  To make the code more robust and efficient, implement a helper class for each effect.  After a while, you may want to find a faster way of adding new shaders Elias Holmlid20

 Complete IDE´s available for developing shaders Elias Holmlid21

 A way to simulate explosions, water, fire etc.  Particles behave in a similar, yet slightly different way Elias Holmlid22

 Particles created and killed on the CPU  Custom vertex declaration used  Pooling should be used (no memory allocation during runtime)  Current position/color/size of each particle calculated in vertex shader  Final color decided in pixel shader Elias Holmlid23
