Renderer using the Escape Time algorithm. For my Computer Graphics course. The key piece is this:. MAX ITERATIONS ;. MAX ITERATIONS ;. In honor of Throwback Thursday, I put together a shader.

Real time computer graphics. June 4, 2014. At the request of a friend from work, I put together a little something with some “ light and shadow. 8220; The trick to basic shadows when working with ray casting is this:. Do a normal ray cast and find your ray intersection with the scene. From that intersection point, try to ray cast toward the light. If an intersection is encountered, the point is in shadow and should be shaded appropriately. Intersect the ray with scene. If we hit a sphere. Finally, we&#82...

Parsing null terminated strings from a stream. May 29, 2015. During a project this week, my project partner and I ran into a problem that is somewhat interesting: how do you parse a string whose delimiters are null characters (‘ 0’)? For example, how do you separate something like this:. This 0is 0a 0null 0character 0separated 0string. 8230;into something like this:. The problem is, of course, that you can’t put this into a. Std: string str = std: string("This 0is 0a 0null 0character 0separated 0string");.

Dot products and saving face. December 3, 2014. In my defense, I had been running low on sleep and energy for a few weeks at that point due to working on a proposal. So not only was I tired, I was cold on writing code. Worse, I hadn’t written a line of graphics-related code in months. These are really just excuses though. Eventually I slogged through to the correct answer, but I felt like I had completely misrepresented myself to this person. Vec4 v ). Endif /* defined( vec4 ) */. Dot product: %.2f n.
