Hello everyone


I saw the function bellow in the book, real time collision detection, and I have to say I don't understand a single thing (math is not my strong subjet) and I would like to...

I am not an expert on the subject and I am reaserching on that too, but you are not suppose to check every object cause as you said is slow. You can do grouping, and insted of cheacking for real...

sorry I couldn't replay back since last time, but I didn't have electricity here, I found out that switching my matrices instead of skinmatrix = inverPose * absoulutematrix I did
skinmatrix =...

I don't want to sound to dumb but doing this ( vertex[n].bindBone[i]->inversePose * vertex[n].bindBone[i]->absMatrix ) what I get is the amount of rotation from the pose to the absolute matrix after...

ups sorry about the
and thank you for fixing it for me, and sorry about the terminology, I have been learning all this stuff on my own and reading that (not school) that have make me a little...

I am new to skeletal animation and I have read that, to animate a mesh using skeletal I would have to use a hierarchy of bones which I did making each bone node in my scene graph and then to deform...

My confusion was since in texture splatting you have a many big square area like regions where many small quads which would have to 1 or 3 texture like grass dirt etc, would be cover with just one...

Hello, everyone

I am working on terrain editor but interested on a way to improve appearance and performance so I put it on a octree, now the texture doesn't look convincing to then I saw the...

so do you think VBO with GL_DYNAMIC_DRAW or GL_STREAM_DRAW will still be faster than VA even when it will be constantly copying the mesh data, is it ok to create a VBO for every object on the scene?

Hello, I have a question on which case to use VBO

I read some tutorial and learn how to make it work, but I have some doubts, on when and how to use VBO for example.

1-I am assuming for a mesh...

the way I used but couldn't posted before I was using the z value of the vector in world space as scale value but multiplying it instead of dividing it as I notice the projection matrix does so the...

can you explain that a little bit please? because since the projection are going to be diferent I don't see how will they be place a same position in screen view

hello everyone,

I am trying to draw many objects that are place on a perspective projection view but that have to look the same size on the pc screen regardless the distance, something like text...

it was basically what you mansion darkphoton I just realize my FromMatrix was row major while the lookat matrix was column major the funny thing was that I thought about it and decided to swap the...

Hi everyone

I am new to the forum and just learning and in top of that I am not a native english speaker so please bear with me.

I am working with some animation and want to make a mesh move...
