figure out if a sketch is in 3d

in Programming Questions • 1 year ago

How can i figure out if a sketch is in 2d or 3d?

If i use bezier with z values in a 2d sketch then i get this:

vertex() with x, y, and z coordinates can only be used with a renderer that supports 3D, such as P3D or OPENGL. Use a version without a z-coordinate instead.

bezierVertex() with x, y, and z coordinates can only be used with a renderer that supports 3D, such as P3D or OPENGL. Use a version without a z-coordinate instead.

And that is probably done by a efficient check (atm i check ik all z values of a pvector are zero).

I did found those 2 pieces of code in http://code.google.com/p/processing/source/browse/trunk/processing/core/methods/demo/PGraphics.java

* Display a warning that the specified method is only available with 3D.

* @param method The method name (no parentheses)

static protected void showDepthWarning(String method) {

showWarning(method + "() can only be used with a renderer that " +

"supports 3D, such as P3D or OPENGL.");

}

* Display a warning that the specified method that takes x, y, z parameters

* can only be used with x and y parameters in this renderer.

* @param method The method name (no parentheses)

static protected void showDepthWarningXYZ(String method) {

showWarning(method + "() with x, y, and z coordinates " +

"can only be used with a renderer that " +

"supports 3D, such as P3D or OPENGL. " +

"Use a version without a z-coordinate instead.");

}

but it seems like those are triggered from pgraphic. http://code.google.com/p/processing/source/search?q=showDepthWarning&origq=showDepthWarning&btnG=Search+Trunk Only i'm stuck here. Can someone help?

In the same file, you can find some relevant methods:

/**
* Return true if this renderer supports 2D drawing. Defaults to true.
*/
public boolean is2D() {
return true;
}
/**
* Return true if this renderer supports 3D drawing. Defaults to false.
*/
public boolean is3D() {
return false;
}
/**
* Return true if this renderer does rendering through OpenGL. Defaults to false.
*/
public boolean isGL() {
return false;
}

These methods are overridden by the sub-classes, of course!
Get the g variable from the current PApplet instance and use these methods from it to know where you are.
