Methods

PaintToBitmap(GeoObjectList, GeoVector, Int32, Int32, Nullable<BoundingCube>)

Paint the provided IGeoObjects onto a bitmap with the help form OpenGL. The viewDirection specifies in which direction the objects are projected (e.g. (0,0,-1) is from top) the objects fill the bitmap and leave a 10% empty frame.

Declaration

public static Bitmap PaintToBitmap(GeoObjectList list, GeoVector viewDirection, int width, int height, BoundingCube? extent = default(BoundingCube? ))

Parameters

Type	Name	Description
GeoObjectList	list	objects to paint
GeoVector	viewDirection	direction of view
System.Int32	width	of the bitmap
System.Int32	height	of the bitmap
System.Nullable<BoundingCube>	extent

Returns

Type	Description
System.Drawing.Bitmap

Events

SetProjectionEvent

Event that is raised when the projection of the OpenGL view was changed. You can modify the light sources and direction. The original code for setting the light model is:

Gl.glLightModeli(Gl.GL_LIGHT_MODEL_TWO_SIDE, Gl.GL_TRUE);
Gl.glEnable(Gl.GL_LIGHTING);
Gl.glLightfv(Gl.GL_LIGHT0, Gl.GL_POSITION, new float[] { (float)v.x, (float)v.y, (float)v.z, 0.0f });
Gl.glLightfv(Gl.GL_LIGHT0, Gl.GL_AMBIENT, new float[] { 0.2f, 0.2f, 0.2f, 1.0f });
Gl.glLightfv(Gl.GL_LIGHT0, Gl.GL_DIFFUSE, new float[] { 1.0f, 1.0f, 1.0f, 1.0f });
Gl.glLightfv(Gl.GL_LIGHT0, Gl.GL_SPECULAR, new float[] { 1.0f, 1.0f, 1.0f, 1.0f });
Gl.glEnable(Gl.GL_LIGHT0);
