john-chapman-graphics: Motion Blur Tutorial

http://www.john-chapman-graphics.blogspot.com/2013/01/what-is-motion-blur-motion-pictures-are.html

Originally posted on 21/04/2011. What is motion blur? Motion pictures are made up of a series of still images displayed in quick succession. These images are captured by briefly opening a shutter to expose a piece of film/ electronic sensor. Later we'll look at a screen space technique for simulating motion blur caused only by movement of the camera. Approaches to object motion blur are a little more complicated and worth a separate tutorial. First, though, let's examine a 'perfect' (full camera. Frame, ...

john-chapman-graphics: "Good Enough" Volumetrics for Spotlights

http://www.john-chapman-graphics.blogspot.com/2013/01/good-enough-volumetrics-for-spotlights.html

Good Enough" Volumetrics for Spotlights. Originally posted on 06/01/2012. I'll be describing a volumetric effect for spot lights, although the same ideas will apply to other types lights with different volume geometries. The volume affected by a spotlight is a cone, so that's what we'll use as the basis for the technique. The basic idea is to render this cone in an additive blending pass with no face culling (we want to see the inside and outside of the cone together), with depth writes. Normalising the ...

http://www.john-chapman-graphics.blogspot.com/2013_01_01_archive.html

Originally posted on 24/09/2012. A while back I published a tutorial. Describing a screen space technique for approximating motion blur in realtime. The effect was simplistic; it took into account the movement of a camera through the scene, but not the movement of individual objects in the scene. Here I'm going to describe a technique which addresses both types of motion. But let's begin with a brief recap:. Is the point right now ( a. Seconds ago ( b. Technically the velocity is.

Chaotic Region

Where thoughts turn into words. Thursday, November 29, 2012. Do anyone over here believes in miracle? I faced the reality, I tried to settle what have been bugging me all the while. Which means, I texted her. You can stop liking or loving some one, but why would you want to stop some one from loving you? I don't get it. She stopped me from loving her. So the question and dilemma here is, do miracle actually happen? Yes I am that desperate. If you are reading this. I'm sorry, I didn't mean to piss you off.
