In this second DVD in our HLSL Shader Creation series, Ben Cloward explores how you can create the main building blocks of a lighting and shading system in HLSL. He shows how you can build shaders to represent the Ambient, Diffuse and Specular components of surface shading. How to enhance your Ambient shading by using a combination of convolved HDRI environment maps and baked Ambient Occlusion. Ben also shows you how to create Point, Directional and Spot light sources. And we wrap up with a practical exploration of some of today’s standard surface shading models, including Phong, Blinn, Cook/Torrence and Oren/Nayar.
This DVD builds on the theory and skills taught in DVD one in this series. You need to know how to write basic HLSL shader code (surface & light) to get the most out of this title.
Inhalt:
CH 01: Normal Mapping Ben starts by looking at how we can use Normal Maps to add surface detail and form to our shading.
CH02: Basic Lighting - Ambient Light We start our exploration of surface shading by modelling the non-directional Ambient lighting component.
CH 03: Basic Lighting - Diffuse Light Now we add in directional diffuse lighting into our shading model.
CH 04: Basic Lighting - Specular Light And we finish off our basic shading model with our Specular highlights.
CH 05: Advanced Lighting - Light Attenuation Now Ben looks at how we can better model our light sources. So, firstly we make our lights intensity diminish over distance, just as lights do in the real world.
CH 06: Advanced Lighting - Directional Lights Next Ben models distant light sources, such as the Sun, with directional light.
CH 07: Advanced Lighting - Spot Lights And finally Ben looks at how we can focus a light into a defined circular throw, with a Spot light.
CH 08: GI - Ambient Occlusion We now move on to look at how we can model our Ambient light component more closely with Ambient Occlusion
CH 09: GI - Using Ambient Cube Maps Then Ben shows us how we can use Ambient Cube Maps to blend in with our Ambient Occlusion maps, and produced enhanced ambient lighting.
CH 10: GI - Creating Ambient Cube Maps And finally we look at how we can create Ambient Cube Maps from our own HDRI images.
CH 11: Lighting Models - Phong/Blinn In this section of the DVD we look at further shading models. Firstly we look at the differences between the Phong and Blinn specular shading models.
CH 12: Lighting Models - Cock/Torrence And then we move on to look at the Cook/Torrence shading model. A shader designed to better model the specular response of metal.
CH 12: Lighting Models - Oren/Nayar And we wrap up the DVD by looking at the Oren/Nayar shading model. A shader that models highly diffuse surfaces.
