opengl es 2.0 framebuffer depth textures

My code is now as follows, fragment shader: #version 330 core I managed to get it working thanks to some help in the comments: GlClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT)

Putting it below the first glViewport call gives the depth image I displayed above though: glBindTexture(GL_TEXTURE_2D, 0) The glClear call where it currently is gives me a completely black texture. Layout(location = 0) out float fragmentdepth

Gl_Position = depthMVP * vec4(Position, 1.0) My depth shaders, vertex: #version 330 core GlFramebufferTexture(GL_FRAMEBUFFER, GL_DEPTH_ATTACHMENT, ssaoDepthTextureID, 0) Īnd the depth pass code I call each frame before regular draw: glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT) ĭepthShader.SetUniformMatrixfv('depthMVP', camera.GetViewMatrix() * Matrix4::Perspective(60, aspectRatio, 0.1f, 10.0f)) GlTexParameteri (GL_TEXTURE_2D, GL_TEXTURE_COMPARE_MODE, GL_NONE) GlTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE) GlTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE) GlTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST) GlTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST) GlBindTexture(GL_TEXTURE_2D, ssaoDepthTextureID) GlBindFramebuffer(GL_FRAMEBUFFER, ssaoFramebufferID) Here's my framebuffer setup code: glGenFramebuffers(1, &ssaoFramebufferID) I've read a lot of sample code online which seems to use regular texture coordinates to draw the depth. I'm at a bit of a loss as to how to fix this. Here's the relevant fragment shader code: #version 330 coreįragColor = texture(uDepthTex, TexCoord0) I'm guessing I need to change this but I don't have a clue what to change it to. Here's what the regular scene looks like:Ĭurrently in my fragment shader I just use my regular texture coordinates (TexCoord0) to draw the depth texture. The texture itself looks correct when I draw it to a quad but I can't figure out how to correctly apply it to the whole scene.

I have created a framebuffer texture to draw the depth to each frame. I've been trying to add SSAO (based on the tutorial here: ) to a project of mine and I've gotten stuck on rendering the depth correctly.
