Reprint here Note: both VAO and VBO are used to store vertex information and send it to vertex shader. As for what are vertices and vertices Shaders , I won't say much here. Readers who don't understand CSDN can do it by themselves. B in VBO means Buffer, which is used to store vertex data; The A of VAO is Array, but ...

openGL series article directory preface In the chapter of lighting and materials, we consider the "luster" of objects. However, we have never looked at very shiny objects Modeling, such as mirrors or chrome products. These objects have a small range of specular highlights and can also reflect the surrounding light A mirror image ...

preface Some time ago, OpenGL will be used in engineering for some rendering and modeling operations. In the future, this column will be updated to explain the application of typical opengl functions and structures in the way of the highest signal-to-noise ratio. Through this hand-in-hand way, I believe it is the fastest way for novice fri ...

Last time, we drew a 30 pixel point with vertex shader and fragment shader. This time, we mainly briefly introduced the functions of each shader, the template for detecting OpenGL and GLSL errors, and the template for reading GLSL source code from the file. Finally, we drew a simple two-dimensional animation. 1, Various shader functions Verte ...

openGL series article directory preface Complex 3D models, such as personas in video games or computer-generated movies, are usually generated using modeling tools. This "DCC" (digital content creation) tool enables people (such as artists) to build arbitrary shapes in 3D space and automatically generate vertices, texture coordi ...

Efficient text rendering with Freetype FreeType is a free font rendering software library. It is written in C language. The design is small, efficient, highly customizable and portable. At the same time, it can produce high-quality output (font image) in most vector and bitmap font formats. Freetype use Header file /* Contains various macro ...

preface At present, the main functions of the mobile camera sdk have been basically developed, and the product has been online for a long time. Looking back on the development cycle, there are many knowledge points in the design of beauty camera, the realization of basic functions is relatively simple, and there are many ready-made open source ...

After the article was published, you have many questions, and I found some very basic. If you ask me to talk more carefully, I'll start again and write more carefully. Although you don't need to look at the code, you may still want to have a comparison when talking about the code. The author uses version 3.6.5, which I have uploaded to Baidu on ...

preface Generally, when adding textures to 3D projects, you often see functions with texture operations. First, look at a piece of chip shader program: in the chip shader #version 450 core out vec4 FragColor; in vec2 TexCoords; uniform sampler2D depthMap; uniform float near_plane; uniform float far_plane; // required when using a perspe ...
