gfx_debug_draw
Library for batched renderering of lines and text in 3D space, using gfx-rs.
Usage
// Initializing...
let mut debug_renderer = DebugRendererBuilder::new(
&mut graphics, // gfx::Graphics
[viewport_width, viewport_height], // width, height of the SDL or GLFW frame/viewport
).build().ok().unwrap();
...
// On viewport resized ...
debug_renderer.resize(viewport_width, viewport_height);
...
// In render loop...
// Draw red line from origin along x-axis
debug_renderer.draw_line(
[0.0, 0.0, 0.0], // Start position
[5.0, 0.0, 0.0], // End position
[1.0, 0.0, 0.0, 1.0], // Line color
);
// Draw an 'X' on the x-axis, at the end of the line drawn above.
debug_renderer.draw_text_at_position(
"X", // String to draw
[6.0, 0.0, 0.0], // World-space position to draw at
[1.0, 0.0, 0.0, 1.0], // Text color
);
// Draw salmoney-colored text 10 pixels down and right from the top left corner of the screen
debug_renderer.draw_text_on_screen(
"Hello World!", // Text to draw
[10, 10], // Pixel coordinates relative to top-left corner of screen
[1.0, 0.4, 0.4, 0.7] // Text color
);
// Submit the final batch of all lines and text for rendering
debug_renderer.render(
&mut graphics, // gfx::Graphics
&frame, // gfx::Frame
camera_projection, // Current camera projection matrix
