Alpha Review

Oops, with alpha review being today I didn't update the blog last night. Oh well.
So I have some progress. I discovered the depth, normal and position buffers, so I worked on the diffuse and specular. I ran into weird problems (I still do at times) with my diffuse being pink even if I didn't set any color. Then it became gray and I was happy and managed to change it to red through the shader (which I wasn't being able to do before for some strange reason) and when I took the color out it was pink again... So, I think I like it red.

I made a video for the review, that I am uploading to you tube later I think.

My plans for the future are to get the OBJ loader in again (I had to ignore it for a while because I need to set up some VBOs and VAOs for the mesh and I felt the buffers were more important), work on the specular and get some lights in.
After that I will try to have my diffuse be a texture and then decide on the extension. I was thinking reflectance fields or light volumes, but I am open to suggestions (please?).

The shortest week/post

I have no pictures to show. Mainly because there is no visible progress.
I have been trying to get the buffers in but I guess there is a lot I need to learn about shaders and GLSL.
Plus I have been sick which totally ate my week from Thursday to Monday...

I found today shaders for deferred shading that come as part of the orange book examples so I guess I could use those. Unless, of course, it is wrong.

And I went from having a black screen to having a gray screen back to having a black screen. I am going to go ahead and pretend that is some progress.
Hopefully I get better soon and can actually work more on this.

So plan for next week is the same as the plan for this week:
-Get the buffers in (somehow)

Another week

On this week's issue we have triangles, in different shapes and colors. We also have a teapot.

I played with the GLSL examples, the triangle one, and changed its color:

Made it smaller:

Since one wasn't enough, I made 2 of them:

 And that was it with the samples.

I then looked into a frame buffer tutorial, made it a project, went step by step and I got a rotating teapot:

And I also read some more. I am re-reading some of my resources since I am closer now to actually doing something that directly has to do with deferred shading.
The end.

I am now in the process of adding the frame buffer to my project. I had it as a Windows Application, hence the GUI, but I think I am changing it to a console application (bye bye GUI). We'll see how that goes. (Opinions, anyone?)

And that is that.

Plan for next week:
- get the frame buffer in, at least depth pass

Some Progress

This past week I have been focused on catching up on GPU concepts and getting the OBJ loader in.

OBJ Loader stories:

I decided to use glm as the loader. But I figured a GUI would be helpful. So, I mixed glm and GLObjViewer and got glmObjViewer, or something. I am basically using the UI from GLObjViewer (since it has the window and the menu nicely in place) and glm as the actual loader. So, I have a bunny!

Joe just told me something to get the models exported from maya as obj to have reasonable .mtl files. I should have a Cornell Box with a sphere and/or cube inside soon enough.

So this part is sort of done, except that now I have to merge this with another project that will help me get up to speed with GPU programming.

Reading stories:

These are boring. I have read. I went through a simple tutorial on GPU concepts, read 2 more things about deferred shading again (to refresh my mind) and I am now in the middle of reading 2 tutorials about framebuffers.

Plan for the week:

-       Merge the 2 projects and play with them (or it, since I am merging them…).

-       Finish reading about framebuffers and start implementing.

-       Anything else that comes up and demands my urgent attention.
