Today we will finish the line rasterization and line clipping stage of the rendering pipeline.
Read the first two sections of this introductory chapter about Java GUIs.
Here are several other introductory chapters about Java GUIs.
Today we will continue to talk about line rasterization and line clipping.
Here is a link to an animation of pixel-plane vs. framebuffer while rasterizing. You need to step to the 14'th page of the presentation.
Here is a formula sheet that documents all the steps that a vertex goes through as it moves down the rendering pipeline, from a vertex in model coordinates to an index in the framebuffer's pixel-array.
Today we will finish talking about the projection stage and start to talk about line rasterization and line clipping.
Read the section about Rasterization and Clipping in Readme_r1.txt from renderer_1.zip.
Play with all these interactive line drawing demos or with this one.
We will continue to use the programs in the folder renderer_1\clients_r1\Position_Model_Vertex_LineSegment to analyze the Model2Camera and Projection stages of the renderer.
Here is a zip file containing several pictures (and a couple of programs) illustrating perspective and parallel projection.
Here are several online demonstration programs of projections and the computer graphics camera.
For next week, read the section about the viewport transformation and the pixel-plane in Readme_r1.txt from renderer_1.zip.
We will use the programs in the folder renderer_1\clients_r1\Position_Model_Vertex_LineSegment to understand the structure of our simplified rendering pipeline.
Remember to read the sections about Model2Camera and Projection in Readme_r1.txt from renderer_1.zip.
Today we will finish with the code in folder "renderer_1\clients_r1\simple_example\".
Next week we will start to talk about the rendering algorithms. Read the sections about Model2Camera and Projection in Readme_r1.txt from renderer_1.zip.
Today we will continue to look at the Scene data structure. In particular, we want to look carefully at the Model data structure. We will use at the code in the sub-folder "renderer_1\clients_r1\simple_example\".
Today we will start to look at the Scene data structure, which is the input data structure for the 3D renderer.
Remember to read the sections about the Scene, Camera, Model, and Position data structures in Readme_r1.txt from renderer_1.zip.
