projectFramefunction
Put the solid, turned by q and zoomed, on a picture width by height: fills every array of the frame.
Import it
import { projectFrame } from "@johnmorrisdotca/meikyuu/3d";Definition
function projectFrame(frame: SolidFrame, grid: SolidGrid, q: Quat, zoom: number, width: number, height: number): SolidFrameParameters
| Name | Type | Description |
|---|---|---|
frame | SolidFrame | The current projected surface-view arrays and dimensions. |
grid | SolidGrid | The valid native flat or surface cell graph. |
q | Quat | The current normalized rotation quaternion. |
zoom | number | The positive surface-view zoom multiplier. |
width | number | The native width in cells or pixels specified by this signature. |
height | number | The native height in cells or pixels specified by this signature. |
Returns
SolidFrame
Put the solid, turned by q and zoomed, on a picture width by height: fills every array of the frame.
