Coding Questions

Hallo,

when i use perspective(fovy, aspect, zNear, zFar) > favy & aspect works as it should

but zNear & zFar change nothing. I use Processing 4.4.10

setup() >P3D & PGraphics matrix...
.
.
matrix.beginDraw();
matrix.beginCamera();
    matrix.perspective(fovy, aspect, zNear, zFar);
    matrix.camera(eye.x, eye.y, eye.z,
                  center.x, center.y, center.z,
                  achse.x,achse.y, achse.z);
    matrix.ambientLight(ambientLightcolor,ambientLightcolor,ambientLightcolor);
    matrix.directionalLight(dl, dl, dl,0,0,-1);
    matrix.lightFalloff(constant, linear, quadratic);
matrix.endCamera();
.
.
.

after cam() i shape different things with matrix.shape(…)

and finally

image(matrix,0,0);

and

matrix.clear();

The strange thing is that when I drive out with the camera, the clipping limit always starts right behind a certain shape.

Does anyone have a solution or idea?

thx…
