# Welcome to :art:CSharpGL
[CSharpGL](https://github.com/bitzhuwei/CSharpGL) is a pure C# project that allows for modern OpenGL rendering in a Objected-Oriented way. It meets common requirements in OpenGL rendering such as:
## :rocket:Modern Rendering
Objected-Oriented modern rendering using GLSL shaders and vertex buffer objects.
## :car:Uniform Variables
structs support setting values for uniform variables in GLSL shader.
## :movie_camera:Camera and Rotator
move or rotate camera to get projection and view matrix.
## :pushpin:Color-Coded Picking
PickableRenderer supports picking primitives in multiple vertex buffer objects using Mouse.
## :volcano:GLCanvas
A winform control that supports drag-drop and wraps initialization of creating OpenGL context.
## :slot_machine:GLControl
Rendering 'Control' at fixed position with fixed size. For example, GLAxis renders an axis at left bottom corner.
'Control' binding to specified border just like winform-control.
## :abcd:Text
Rendering text using ``glRasterPos()`` and CallList.
Rendering text using GLText(a special GLControl).
## :tea:Some Models
A Cube, Sphere, Teapot and some other models.
## :cancer:GLSwitch
Wraps OpenGL commands like
```
glEnable(GL_BLEND);
glBlendFunc(GL_SOURCE_ALPHA, GL_ONE_MINUS_DST_ALPHA);
```
or
```
glLineWidth(2.0f);
```
## :ideograph_advantage:Converting TTF file to picture
The project CSharpGL.Font2Picture in :open_file_folder:`Infrastructure` is a quick tool converting TTF files to pictures along with a xml config file.
