Webcam Capture Loads Blank Pixel Array in P2D/P3D

[aidanlincolnn]

Description

When you create a canvas with P2D or P3D, the webcam capture does not contain any data (it is an array of black pixels).

Expected Behavior

The capture object pixel array should contain data

Current Behavior

The capture object pixel array contains all black

Steps to Reproduce

Run this program
import processing.video.*;
Capture video;
PImage theImage;

void setup() {
//this loads an array of black pixels
size(640, 480, P3D);
//this works as expected
//size(640, 480);
video = new Capture(this, 640, 480);
video.start();
}

void draw(){
if (video.available()) video.read();
theImage = video.get();
theImage.loadPixels();
image(theImage,0,0);
}

Your Environment

• Processing version: 3.5.4
• Operating System and OS version: OSX Catalina 10.15.4

Not sure if the webcam has anything to do with it, cause this results in an array with only zero's as well:

PGraphics pg;

public void settings() {
    size(512, 512, P3D);
}

public void setup() {
    pg = create_some_graphics();
    pg.loadPixels();
}


public void draw() {
    background(0);
    image(pg, 0, 0);
}



PGraphics create_some_graphics() {
    PGraphics pg = createGraphics(512, 512, P3D);
    pg.beginDraw();
    pg.background(0);
    pg.pointLight(255, 0, 0, 0, height/2, 500);
    pg.pointLight(0, 0, 255, width, height/2, 500);
    pg.pointLight(0, 255, 0, width/2, 0, 500);
    pg.translate(width/2, height/2);
    pg.rotateY(0.01f * random(123));
    pg.rotateX(0.05f * random(456));
    pg.rotateZ(0.07f * random(789));
    pg.fill(255);
    pg.sphere(150);
    pg.box(500, 20, 20);
    pg.box(20, 500, 20);
    pg.box(20, 20, 500);
    pg.endDraw();
    return pg;
}
