Description
Rendering lines or spheres on the screen works fine. When we render spheres to PDF or SVG, they are depth sorted properly. However, lines are not depth sorted; they are drawn in the order of declaration.
Expected Behavior
Lines should also be drawn according to their depth ordering (at least with hint(ENABLE_DEPTH_SORT)
enabled).
Current Behavior
Lines are currently drawn according to their declaration order (even with hint(ENABLE_DEPTH_SORT)
enabled).
Steps to Reproduce
Comment/uncomment each line that appears in draw()
.
import processing.pdf.*;
import processing.svg.*;
void setup()
{
size( 500 , 500 , P3D );
hint( ENABLE_DEPTH_SORT );
}
void draw()
{
// Choose one:
//drawToScreen();
drawToPDF();
//drawToSVG();
}
void drawToPDF()
{
// Here we generate the PDF document.
beginRaw( PDF , "output.pdf" );
drawMyStuff();
endRaw();
exit();
}
void drawToSVG()
{
// Here we generate the SVG image.
beginRaw( SVG , "output.svg" );
drawMyStuff();
endRaw();
exit();
}
void drawToScreen()
{
// Here we just draw to the screen.
drawMyStuff();
}
void drawMyStuff()
{
background(255);
lights();
strokeWeight( 50 );
// First we draw the line that should be shown on top (black).
stroke( 0 , 0 , 0 );
line( 250 , 50 , 100 , 250 , 450 , 100 );
// Then the line that should be shown behind (red).
stroke( 255 , 0 , 0 );
line( 50 , 250 , -100 , 450 , 250 , -100 );
stroke( 0 , 0 , 0 );
strokeWeight( 1 );
// First, draw a green sphere that should appear on top.
pushMatrix();
fill( 0 , 255 , 0 );
translate( width*4/10 , height*4/10 , 50 );
sphere( 70 );
popMatrix();
// Then draw a blue sphere that should appear behind.
pushMatrix();
fill( 0 , 0 , 255 );
translate( width*3/10 , height*3/10 , -50 );
sphere( 70 );
popMatrix();
