OpenTK.3D.Library 1.3.2.4

OpenTK3DEngine

Example code:

1. Add a new .cs line to your console app, that will be your main place to code
2. On your program.cs file add the example code no. 2,
3. If you dont want the console opening change your project properties to Windows Application

Current Available Functions

On OnLoad

1. Make sure to add these after base.OnLoad()

2. createMainLight(Vector3 pos, Vector3 color) ⇒ Creates your main Light (static), make sure to run this function before any other 3D function but after Base.OnLoad(),

3. createCube(Vector3 Color) ⇒ Creates a 3D cube of the color you specify, returns a handle for making modifications to the cube,

4. createSphere(Vector3 Color) ⇒ Creates a 3D sphere of the color you specify, returns a handle for making modifications to the sphere,

5. createTorus(Vector3 Color) ⇒ Creates a 3D torus of the color you specify, returns a handle for making modifications to the torus,

6. createCylinder(Vector3 Color) ⇒ Creates a 3D cylinder of the color you specify, returns a handle for making modifications to the cylinder,

7. public int createPlane(float x1, float y1, float z1, float x2, float y2, float z2, float x3, float y3, float z3, float x4, float y4, float z4, Vector3 color) ⇒ Creates a 3D plane of the color you specify, returns a handle for making modifications to the plane,

8. openTexturedObj(string obj, string texture) ⇒ Opens .obj file with an attached .png texture, returns a handle for making modifications to the object,

9. openObj(string obj, Vector3 color) ⇒ Opens .obj file with no attached .png texture, returns a handle for making modifications to the object,
