apptest_shaders

A test that shows the custom shaders API and how to do post-processing with viewports. You will see regular sprites, mesh sprites, and some multi-textured normal mapped sprites, all using custom shaders and with batching!

The ImGui interface will allow you to tweak the lighting parameters for normal mapped sprites and change the post-processing between bloom (using multiple render targets and downsampling) and a separable Gaussian blur.

Controls

• Use the mouse, the keyboard, the gamepad, or the touch screen to interact with the ImGui interface
• Dragging the mouse while pressing the left button, touching with one finger, or moving the left gamepad stick will move the light
• Pressing B on the keyboard or A on the gamepad will toggle batching
• Pressing C on the keyboard or B on the gamepad will toggle culling
• Pressing T on the keyboard or X on the gamepad will toggle between individual textures and a texture atlas (more chances for batching)
• Pressing Y on the gamepad will reset the light position to the center of the screen
• Pressing R on the keyboard will toggle between the original and the custom shader for regular and mesh sprites
• Pressing V on the keyboard will toggle between different no post-processing and blur
• Pressing L on the keyboard will toggle between different no post-processing and bloom
• Pressing the right bumper on the gamepad will cycle between no post-processing, blur, and bloom
• Pressing 1, 2, or 3 will change the number of blur passes in post-processing
• Pressing CTRL + H on the keyboard will show or hide the ImGui interface
• Pressing F on the keyboard will toggle full screen
• Pressing P on the keyboard or Start on the gamepad will pause the application
• Pressing Escape on the keyboard or Guide on the gamepad will quit the application
