I Did some more exercises from Directx 11 book. Chapter 11 The Geometry Shader had couple interesting exercises. First one was exercise 3 that asked to implement a simple explosion effect in geometry shader to an icosahedron where each triangle are translated to the direction of their face normal as a function of time. The…
Chapter 10 teach about stencil buffer and using it to mark a mirror from drawing a reflection or to use it to draw planar shadows. ex 3 asked to produce image on figure 10.1 left side where all of the reflected skull was rendered not only the mirror part. This can be achieved by changing…
Chapter 9 blending had few exercises that asked to make small modifications to blending demo and to experiment with different blend operations and blend factor combinations. I changed some blend operations and made the water look in the demo like a poisonous cloud or some other strange color Also…
I have been re-reading Frank Luna’s DirectX11 book and also doing some of the most interesting exercises that are in end of each chapter. I will post some of the exercise solution snippets so I can review them easier later and use them if I need. Texture sampler address modes Chapter 8 discussed texturing and…
I finished the chapter 7 of the book 3D Game Programming with DirectX 11 that discussed about lighting model and different light types: directional light, point light and spot light. ex. 1. asked to modify light colors of the chapters lighting demo. ex.2. asked to modify the specular power (p) of the materials in the…
I did some Exercises from Directx 11 book chapter 6 Drawing in DirectX. Some more interesting screenshots and some code snippets from exercises. ex.4 ex.6 Simple cube animation on vertex shader. Added code to C++ shader code: ex. 13 Setting and using scissor test. ex. 14 GeoSphere with different subdivision levels. Subdivision levels: 0, 1…
Finished chapter five The Rendering Pipeline discussed about different stages in the dx11 rendering pipeline and e.g. how to define the view matrix and the perspective projection matrix and 2d projection. Most of the exercises were something like given some values find perspective projection matrix or find vertical field of view angle, frustum corner vertices…
