In the previous articleArticleIn this example, we know how to draw a 2D image in the 3D coordinate system, that is, draw a triangle, this time, we need to know how to present a 3D image in a 3D coordinate system and how to understand several coordinate systems in a 3D space.

The normal plane effect can be achieved by changing the horizontal and vertical coordinates. With the addition of depth, 3D effects can be visually produced. The program simulates such a three-dimensional space, and the images in the space are displayed according to the three-dimensional coordinates. I have seen a 3DRoom effect a long time ago and it is implement

IntroductionIn the previous section, I described how to implement a ray-to-triangle cross-detection algorithm. However, we should know that in game development, a model has a lot of triangles, if you want to all objects, all the triangles to do this detection, even if the current computer computing ability, is not efficient to complete. Therefore, we need to use other means to remove some of the objects that are not likely to cross, this early thinking, a lot of use in

The program is to simulate such a three-dimensional space, inside the picture will be based on three-dimensional coordinates displayed in this space. I've seen a 3DRoom effect a long time ago, it's done with complex computations. After the previous image transformation studied CSS3 's transform, a simpler way was realized.

This article is part 1 of 3D basics. It mainly describes the calculation principle of vertex tangent vectors. I believe many people do not have a deep understanding of the tangent component in the shader.ArticleIt is helpful for everyone. We use the concave-convex ing as an example to explain the principle of today. In fact, the disturbance values stored in the concave and convex textures are actually based on x y in the figure (for details about th

as the whole world's geometric mipmapping. The editor in the game allows the player to edit the map in real time after entering the map. That is to say, when flying in the map, you can click it to edit what you see. In addition, maps do not need any pre-compilation actions, and even projection is completed in real time. This is a powerful open-source engine. It seems a good learning opportunity for game developers or game R D companies that want to study FPS. The engine of perfect time an

In AE development, we often encounter the need to export the current scenario in map, scene, and globe as an image. below is my summary of the export method, where two-dimensional can be exported to the memory or hard disk, you can also export the space data file of the image, which can only be exported to the hard disk in 3D, with the source code (VB. net), the usage is detailed in summary, ^ _ ^ ''' ''' T

Objects in 3D space move at a certain speed and sometimes require the object to be oriented in the same direction as the velocity,In order to achieve this goal we generally use the rotation matrix M to rotate the object to the corresponding orientation.For example, the velocity direction vector Spdv:vector3d (The x-axis base vector is Axis_x:vector3d (1,0,0), and the direction of the vector is aligned with

When I was a beginner at 3d, a concept had plagued me for a long time: What is vertex and what is vector ?? In the program, vertices and vectors are represented by the same type. Even discussed with others, the two are also mixed, so they were confused in the beginning. In fact, vertices and vectors are different concepts. Vertex: the location information in the space, that is, the coordinates of X, Y, a

Difficulty: when constructing the vertex coordinates of a 3D space, to make the object rotate around its own axis, the central coordinates of the object must always be (0.0f, 0.0f, 0.0f ), and the triangles are drawn in a counter-clockwise order. 2.3D space painting: GL_APICALL void GL_AP

This is the 3rd part of the 3D Foundation, mainly about the vertex tangent vector calculation principle, I believe that many people are shader in the tangent components do not have in-depth understanding, I hope this article can help you understand the cutting space. We use the bump mapping as an example to explain today's principles. In fact, the found perturbation value stored in the bump map is actually

Introduction Ray has many important applications in 3D graphics. For example, the pick operation is implemented by Ray, and Ray can be used for bullet Ray collision detection. Therefore, in this blog, we will briefly introduce how to perform Ray-triangle cross detection. Ray-triangle crossover Detection Algorithm In the Mt97 thesis of Tomas Moeller, a new algorithm is proposed. This algorithm reduces the memory consumption required for Ray-triangle
