◆ dglGetViewport()
| void dglGetViewport |
( |
RectI * |
outViewport | ) |
|
gets the current viewport of the window
◆ dglIsOrtho()
returns whether or not the coordinate system is orthographic (if it is not projected)
◆ dglSetClipRect()
| void dglSetClipRect |
( |
const RectI & |
clipRect | ) |
|
Sets up an orthographical viewport and clipping region. This is best used for guis
- Parameters
-
| clipRect | The bounds of the coordinate system |

bool |
ortho = false |
|
) |
| |
Sets the viewing frustrum. This effectively creates the view volume and sets up the 6 clipping planes (near, far, left, right, top, bottom)
- Parameters
-
| left | This is the position of the left vertical clipping plane |
| right | This is the position of the right vertical clipping plane |
| top | This is the position of the top horizontal clipping plane |
| bottom | This is the position of the bottom horizontal clipping plane |
| nearDist | This is the distance between the eye and the near clipping plane |
| farDist | This is the distance between the eye and the far clipping plane |
| ortho | (optional, default is false) If left false, calling this function will create a projection viewing volume. If true, it will be orthographic |
◆ dglSetViewport()
| void dglSetViewport |
( |
const RectI & |
aViewPort | ) |
|
sets the viewport for the window
