Maybe Im doing it the wrong way but it is the same but a loooot :_) slower. Here is the code:
import processing.opengl.*;
ground new_ground = new ground();
float c_x,c_y,c_z;
void setup(){
size(1000,1000,P3D);
frameRate(30);
new_ground.setup();
frustum(-500,500,-500, 500, 200, 0);
}
void draw(){
background(0);
new_ground.draw();
camera(c_x,c_y-200,c_z,c_x + 200*sin(map(mouseX,0,width,0,TWO_PI)),c_y -200 ,c_z + 200*cos(map(mouseX,0,width,0,TWO_PI)),
0.0, 1.0, 0.0);
}
void keyPressed() {
float move = +500;
if (key == CODED) {
if (keyCode == UP) {
c_z = c_z + move;
} else if (keyCode == DOWN) {
c_z = c_z - move;
} else if (keyCode == LEFT) {
c_x = c_x + move;
}else if (keyCode == RIGHT) {
c_x = c_x - move;
}
}
}
