Object Oriented OpenGL in C#

🔮Wiki | 🥚nuget | 🍞CSharpGL.dll
CSharpGL is a 3D graphics library based on OpenGL in pure C#. It wraps OpenGL API(buffer, shader, state, texture, matrix etc) and demonstrates how to express high-level functions(scene, text, picking, UI etc) with CSharpGL library.

📌Color-Coded Picking

IColorCodedPicking supports picking primitives in multiple vertex buffer objects using Mouse.
pick and move primitive

🔘☑️UIRenderer & Text

Rendering 'Control' at fixed position with fixed size.
For example, UIAxis renders an axis at left bottom corner.
All kinds of controls binds to specified border just like winform-control.
Rendering text using glRasterPos() and CallList().(Obsolete)
Rendering text using UIText.

Generated Klein Bottle.

Earth.

An earth model that singly rotates same as real earth. It's composed of 65341 positions, normals and uvs and 130140 indexes and a 10800x5400 texture. earth

🆔💯Billboard and LabelRenderer

Billboard can be used to display health-bar, damage numbers in game application. LabelRenderer renders a string at specified position which always faces camera.

🔆Light

ambient, diffuse and specular light effect from directional light.

🎥Scene Editor

Useful tool to build a scene and feels how opengl's transform system works. CSharpGL-Scene-Editor

🍟Renderer Generator

RendererGenerator is a tiny console that reads an xml config file and dumps a Renderer.cs, a Model.cs, a vertex shader file(.vert) and a fragment shader file(.frag). A demo is shown as below:

<?xml version="1.0" encoding="utf-8"?>
<RendererGenerator TargetName="Demo" ZeroIndexBuffer="false" DrawMode="Points">
  <VertexAttribute NameInShader="in_Position" NameInModel="position" AttributeType="vec3" />
  <VertexAttribute NameInShader="in_TexCoord" NameInModel="texCoord" AttributeType="vec2" />
</RendererGenerator>
