Hello,
I’m currently working on a project using the Juce framework. Everything works great. Except that I have some problems to use the OpenGL.
Let me explains first what I do.
So I have an openGLContext set on a component. (To be sure that it would works, I took the OpenGLDemo file existing in JuceDemo, and I delete everything and keep the basis). I was able to do what I wanted to do with OpenGL. What I draw is just simple colored polygon, nothing asking a high level in OpenGL. Here is my code
glBindTexture(GL_TEXTURE_2D, texture->getTextureID()); glBegin(GL_POLYGON); for(unsigned int i = 0; i < m_ vertices.size(); i++) { glVertex3f(x,y,z); } glEnd(); glBindTexture(GL_TEXTURE_2D, 0);
It works well on desktop OS, but it fails on mobile OS, but I figured out it was normal. And this is where my problem began.
After a lot of research (mainly in this forum), I find out, that it should have worked with OpenGL ES1.x. But as the openGLContext is set for OpenGLES 2.x, it is normal that my code doesn’t compile for mobile devices.
I also find out at the same time that the original JuceOpenGLDemo doesn’t work on iOS (the cube drawn in OpenGL is not displayed).
I did some extra research. I find out that Juce don’t support the OpenGL on iOS. I read several discussion, where people are testing some stuff to make it work, but unfortunately, there is no return about their own solution.
I also try on my own to draw just a polygon, inspiring from a tutorial on OpenGLES as I’m not an export in OpenGL and OpenGLES. It didn’t’ work, but I don’t know if the problem is me, or Juce. So my problem is that I have problem to know if I can use “pure” openGLES methods, or if I have to do something (like setting up the view using some Juce methods).
I just need to draw polygons in the 3D space, without any complicated effects. I just fill them with a uniform color or a simple texture.
I'm currently stuck with these openGL problems :(
So, I'm trying to find some advices, or a little help or anything that could help me to resolve the problem.
Thanks in advance for you help !
