Custom Cursor in 3D ?

Programming Questions

Hey,

sorry for posting all this (silly?!) questions but I can't even find an answer via google (just for processing alpha and this doesn't seem to work…)

I want a custom cursor in a 3D processing script, in 2D everything went well, code:

void setup () {
size(300, 300);
}
void draw () {
noCursor();
background (255);
KREUZ(mouseX, mouseY);
}
void KREUZ (int x, int y)
{
line (x-(width+x), y, x+(width-x), y); //KREUZ X achse
line (x, y-(height+y), x, y+(height-y)); //KREUZ y achse
}

I also tried to generate the cross in a .svg and load it as cursor(cross.svg)

in both variations I have the same problem:

as soon as i put it outside of the push popMatrix() which sets up my object it lies BEHIND it … not in front …

sounds like a simple problem but I don't get it neither…

thanks a lot for your help again…

You should definitely use the cursor() method...
It shows up behind the rendering? Can you show an example that causes this?

well i tried it by cursor() but processing tells me that I'm not allowed to use a void as cursor…

so I tried to create just the cross in the end of the draw but it is also behind the scetch…

errrrr… I can give you my sketch but you have to load an image in ?

I have a map and generate objects on this map so the draw are two huge push popMatrix()' for the translate commands

here my draw:

void draw()
{
background(bg);
smooth();
directionalLight(126, 126, 126, 0, 0, -1);
ambientLight(102, 102, 102);
//tentakeln
tentakel1 = new Tentakel(15, 35, 15, r, g, clicked);
tentakel2 = new Tentakel(80, -155, 15, 0, 255, clicked);
//tentakeln.ende
//popup
popup1= new Popup("Tankstelle 1", sprit[0], preisliste[0], preisliste[1], preisliste[2], 25, 9, allgemeinerschnitt);
popup2= new Popup("Tankstelle 2", sprit[1], preisliste2[0], preisliste2[1], preisliste2[2], 25, 9, allgemeinerschnitt);
font = loadFont("light.vlw");
//popup.ende
//target abfrage für interpolation…
if (mouseIsPressed) {
int diff = mouseXVal - mouseX;
target = rotnew - diff * 0.01;
}
mouseXVal = mouseX;
// println(target);
//targetabfrage.ende
pushMatrix();
rotx= width/2+dragx;
roty = height/2+dragy;
translate(rotx, roty);
rotnew = interpolate(rotnew, target);
translate(0, 0, zoom);
rotateX(radians(-25));
pushMatrix();
rotateY(rotnew);
rotateX(radians(90));
pushMatrix();
tentakel2.gentent();
popMatrix();
pushMatrix();
tentakel1.gentent();
popMatrix();
pushMatrix();
ghost1.gentent();
popMatrix();
pushMatrix();
ghost3.gentent();
popMatrix();

ghost4.gentent();

ghost5.gentent();

popMatrix();
popMatrix();
}

(KREUZ(mouseX,mouseY) was added in line 9)

here a picture, the 2 golden lines should be the cursor ?!

I don't know how advanced you are

but referring to

void KREUZ (int x, int y)
{
line (x-(width+x), y, x+(width-x), y); //KREUZ X achse
line (x, y-(height+y), x, y+(height-y)); //KREUZ y achse
}

:

Did you know line also comes as a 3D command?

Then you can go like

line( x1 , y1 , z1 , x2 , y2 , z2 );

yep like told above I know the cursor() command and everything wents well with, CROSS WAIT etc but NOT with an custom shaped one :/ The hint that lines can be 3D is a good one ! Absolutelly forgot about that !

Thanks I will try that in a free minute !
