If you need me to write some examples and analysis to realize a function in your study or work, you can clearly describe the function after this article, reply in the comment area or leave a message in the group, and I will help write some examples a ...

reason Group Friends: challenge a high starting point. I asked such a question in the group: So I think it's confused about the viewport defaults and rotation of the operator. If you don't make it clear, basically many things can't be done later. I'm going to write a small example to help you sort it out. The complete code is at the end of t ...

Previously, we introduced the simple method of flattening objects to the projection plane to create shadows. However, this shadow method has its limitations (for example, the projection plane must be a plane). In opengl1 4 introduces a new method shadow map to generate shadows. The principle behind shadow mapping is simple. We first take the p ...

1. Theoretical knowledge OSG finally draws osg::Geometry, and then the Geometry will be stored in the Node. For example, if we want to draw 10 lines, we have two methods. One method is to define 10 Geometry, and each Geometry defines two vertices to draw one line. Another method is to define a Geometry with 20 vertices and draw 10 lines at one ...
