We are also gonna measure this performance change by making an FPS counter. So face culling is a step in the graphics pipeline that decides if a triangle will move on to the fragment shader (aka, if the triangle will be drawn or not). OpenGL decides this by seeing which side of the triangle is currently facing the camera. .. 더보기 OpenGL tutorial 11 (Stencil buffer & outlining) The Stencil bufferis use to create outlining effect. the Stencil Buffer, just like the Depth Buffer, holds a value for each pixel, these values being used for image masking in general. Unlike the Depth Buffer though, where each pixel holds between 2 and 4 bytes of data, for the Stencil Buffer each pixel only holds 1 byte of data, so values from 0 to 255. But you'll mainly only use the values of .. 더보기 OpenGL tutorial 10 (Depth) // Enables the Depth Buffer glEnable(GL_DEPTH_TEST); Since the buffer is turned off by default, we want to make sure we have it enabled, and that we clear it each frame just like the Color Buffer. Now what this buffer basically does, is that it stores "depth" values that represent how far away from the near plane of the projection matrix a certain fragment is. (The depth value represents 0 to 1... 더보기 OpenGL tutorial 9 (Model Loading) https://youtu.be/AB_f4slL2H0 opengl에서 가장 복잡하지만 가장 필요한 파트. the image file format is pretty standardized with png and jpg. but the model is not, there are dozen upon dozen of file format. the diversity of file formats makes a lot more difficult to export and import models, from one program to another. in the spirit of standardization, we use the glTF file format. the glTF is made by same people wh.. 더보기 OpenGL tutorial 8 (Mesh) We'll warp up all the classes Mesh is a data set that almost always contains vertices, often contains indices, and somtimes contains texture. the tree of our classes dependencies. we will declare three vectors named vertices, indices and textures. note that these are c++ vectors, instead of glm vectors (c++ vector is dynamic array) 1. store our VAO since we'll be initializing it using this class.. 더보기 이전 1 2 3 4 ··· 8 다음
