OpenGl

Question

is Opengl easy to learn or not
i am looking forward to OpenGl course online

Answer 1

Abdul Rehman, it's not easy!
I tried webGL which is basically a subset of openGL, and does not require native driver support and used in web browsers

it gives you complete GPU access and you have to control all the parameters ( big headache in 3d animations)

we generally use a gpu codes called shader codes that are executed in GPU.

figuring out the
-attributes/buffers
-uniforms
-textures
-varyings

for your shader codes is complicated.

Basically it cares about 2 things
1. coordinates ( vertex shader code)
2. colors ( fragment shader code)

even The hello world level code in pure openGL has quiet a learning curve to it

Answer 2

Thanks @Morpheus for your valuable Advice ☺😊

Answer 3

I couldn't continue it because I m studying animations as a hobby, and without any supporting libraries like three.js etc , studying pure webGL or openGL is pretty time consuming.
