OpenTK Example - FBO / Render Target TV

Available on Github

This is a small example of how to use a framebuffer object (sometimes the output is called a render target, although that's more of a DirectX term) in OpenTK. There's a second camera in the scene with its position indicated by the arrow. What that camera sees is put into a texture and then displayed on a model of a TV.

This is also significant because it allows us to get the depth information of the scene. This allows us to create shadows later by easily determining if there is an object closer to the light (which would have a camera "seeing" from its direction above or in the scene), and darkening parts where that is true.

Controls:

• WASDQE - Move main camera
• UHJK - Move texture camera
• C - Switch between color view and depth view
• V - Toggle TV static shader on/off

Inside the Sprite Example

Last time I posted a new example that uses OpenTK for a 2D view with sprites. Let's go into a bit more detail about how it works:

OpenTK Sprites Example

A new example is available on the GitHub repository:

https://github.com/neokabuto/OpenTKTutorialContent/tree/master/TKSprites

This example features 2D drawing of textures, with motion and alpha blending. 30,000 sprites are added by default, but you can add more by hitting the + key. Most of the sprites are off-screen (and not drawn to help keep things running smoothly), but you can move the view with the arrow keys (and speed up with the shift key) to pan around the world. Clicking on one of the sprites will change its texture! 

UPDATE 3-11-15: New feature: multiple shaders! Hit V to change which shader is used, or hit M to toggle a mode where the shader is chosen based on the texture.

OpenTK Tutorial 6 Project File now on GitHub

Missed having OpenTK content? Good news, I'm working on making more of it soon! Up next is a demo on using orthographic projection with what we've covered in previous tutorials to make sprites (as requested by an anonymous commenter a while back).

While you all wait for that, the basic textures tutorial project is now up on GitHub:

SFML.Net Example: Breakout Clone

Here's a second basic SFML.Net example. This time it's a clone of the game Breakout (copyright Atari, please don't sue).

SFML.Net Example: Pong Clone

Here's an example of a simple game made in SFML.Net. It's a clone of a certain well known table-tennis game that tends to be a common early project. Try to hit the ball off the right side of the screen while the computer attempts to do the same to the left side of the screen.
