Software

Software I've Made

I dabble in a bit of everything so I get to know a little about a lot of things( being a generalist here)
and have been trying recently to focus on fewer stuff. So mainly stuff related to graphics programming with OpenGL and writing shaders have been my main focus as of late.
I also work on my own game engine ( Para Engine ) and various other pieces of software ranging from QR Code Generators to Image Processing Tools and Shader IDEs.

So as I've said, I dabble a lot so some of the technologies that I have come across include OpenGL, Unity, WPF, WinForms, Processing Framework and many more.
The main projects that I have done and will keep improving upon (hopefully) is my Game engine and my Code Summarizer ( Takes C# Code And Makes HTML Output With Documentation ).
I have all my work posted on my Github and some the major work I have done along with source code and a ready to use binary can be found here.

Fortnite Procedural Construction Animation Shader

Fortnite Construction Shader This shader is loosely based on the one that was presented by the Fortnite developers in their GDC talk: Inner Working Of Fortnite's Shader-Based Procedural Animations.

 Here is what we will end up with:
This technique requires you to author the 3D model in a certain way, More or less how those Fortnite developers did.
So we need the authored 3D model and the shader that uses data we get from the model to achieve the desired effect.

There are some nuances here and there so make sure you don't miss out on the details.😗
The first step will be preparing the 3D model and putting in the required data. I used Blender 2.79 but any 3D modeling software would do.

Apply Vertex Colors: For the direction of flight
Each color is a component of a vector (x, y, z). This will be considered as local space.
Values range from -1.0 to +1.0 for each component.
Negative values are achieved by using values of less than 0.5 and positive values wi…

Advanced Billboard Shader + World-Space UI Support

Advanced Billboard Shader + World-Space UI SupportAs you know billboarding is basically a plane with a texture on it that always facing the camera.These are some examples of what we are going for. This tutorial is going to be pretty straight-forward and easy to follow along you will learn how to make a billboard shader that not only keeps looking at the camera but also keeps its relative scaling intact.We will also provide an option to keep it rendered on top of all the other objects in the scene. This will be most useful for world-space UI that needs to be rendered on top of other geometry.We will be making 2 shaders here,Modified Default Unlit shader :- This one is a general shader ( easy to modify furthur ).Modified Default UI shader :- This one supports whatever a UI shader supports along with our billboarding capabilities. So let's get started with making the first one. As usual create a new Unlit shader and dive into the properties we need.Properties { _MainTex ("Texture…

Get Started With Compute Shaders

Getting Started With Compute Shaders The shader that's a 'Jack of all trades'. Of course, it's the Compute Shader.
These beauties allow your general purpose parallelized code to run on the GPU.
These can be used to do some pretty cool stuff that would be pretty difficult to do otherwise even with multi-threaded CPU code.
When bringing up Compute shaders in the context of video games, It's mostly used in physics simulations and freaky looking particle effects and to a lower extent as a core part of some post-processing effects and render pipeline optimizations such as various culling operations like occlusion culling.

The most important thing about compute shaders is that it allows for more efficient communication from CPU to GPU side and vice-versa. That basically means you can send arbitrary data to the GPU, let it do some work and then read it's output and then do whatever you want with it.
You can now see that how different compute shaders are when compared …
