Direct3D or OpenGl?

[Wahrheit]

Hi ,

 

I started to code in C# 3 weeks ago.

 

now iam able to code with MySql and C#.

 

but now i wanna learn how to use Models and texture / animation in my progamms.

 

i heard about OpenGl and Direct3D.

 

 

i want to start with Direct3D but first i wanna hear ur oppinion what i should learn : OpenGl or Direct3D?

 

would be rly nice to hear ur opinion about that.

 

[Why i am learning C# etc? because i wanna do some software/game developement in my future work.I am 15 now and i wanna have some knowledge until im on a university or something like that.I have knowledge in PHP and a little in JAVA]
