Procedural Terrain Generation

I had written a post on texture generation using procedural noise. I use the same technique to generate a terrain. The explanation of this code is in this site: http://lodev.org/cgtutor/randomnoise.html


Here is a snapshot:

Here is the code.

Diamond Square Algorithm in C/C++

I have implemented the Diamond Square Algorithm as depicted in this site =>https://www.bluh.org/code-the-diamond-square-algorithm/

It is a way of generating height maps for computer graphics. These height maps can be used as textures or landscapes. It is a slightly better algorithm than the three-dimensional implementation of the midpoint displacement algorithm which produces two-dimensional landscapes. It is also known as the random midpoint displacement fractal, the cloud fractal or the plasma fractal, because of the plasma effect produced when applied.

For further details refer: https://en.wikipedia.org/wiki/Diamond-square_algorithm

I chanced upon this topic while searching for Fractal Terrain Generation.

Object Model Loader in C++ using OpenGL

There was demand from some students to have an object model loader in C++ and I was trying it since so many days.

The one I am posting is incomplete. It has some issues such as elephant and teddy not loaded properly.

As you can see when I plot each vertex in the object model it seems fine:

But when I draw the triangles It comes with holes.

As shown here:

The model must be incomplete or the program has some bugs, I am not sure what is going on. If anyone could point out the flaw its hugely welcome. On further probing I found that the error seems to be while parsing the input .OBJ file. Certain files have two white spaces between f and the vertex index and some files have an extra blank at the end of each line. I have worked with same files in JAVA and there because of robust string handling functions these minor hiccups do not arise.

Here is the code in C++.
