Where did graph.curve.opengl.TextRenderer go ?

Hello,

I updated my libraries to the JOGL March 2015 version and com.jogamp.graph.curve.opengl.TextRenderer doesn't exist any more . Did it move?

I tried the alternative (com.jogamp.opengl.util.awt.TextRenderer) but I can't get it to work with GL3.

Thank you for your help.

TextRenderer has been replaced with TextRegionUtil

API Changes:
      - OutlineShape, Region, ...: See above
      - Removed TextRenderer, GlyphShape and GlyphString: Redundant
      - Added TextRendererUtil to produce the Region from CharSequence

I see. Thank you Xerxes Rånby!

I tried to run a very simple example. It seems to work fine until I enable the depth test. When  I enable it the text doesn't show. It doesn't give me any errors.

depth is tricky, since we talk about an approx. 2D figure,
which then shall be upfront all other elements (z-axis)
and be rendered at last (back-to-front).
Following the above .. it does work, see our UI test renderer,
which sorts all elements by its z-axis.

Our UI test disables depth for all opaque elements
which are transparent.

I got it to work with enabled depth test somehow.
Now I added another 2D object to my scene that uses my shaders.
I can't figure out how to make both the text and the other 2D object to show up. With the old text render I used gl.glUseProgram(shaderState.shaderProgram().program()) and gl.glUseProgram(myOwnProgram) to switch back and forth. However, it doesn't work now. RenderState.IsShaderProgramInUse() give me FALSE. I don't understand what program to use.

Currently it seems that integration of user GL code
w/ RegionRenderer and RenderState is poorly supported,
sorry about that!

A workaround would be to use
  RenderState.setShaderProgram(final GL2ES2 gl, final ShaderProgram spNext) {..}
which will notify the RenderState about the ShaderProgram switch.

We shall have an API entry either to simply flush RenderState's
current state or add a flag to _force_ the 'setShaderProgram(..)' switch.

Maybe both will be beneficially.

Would you be so kind to add a bug report w/ this knowledge?
In case you like to make this change yourself, pls go ahead
and offer a git patch (mail, your-repo/branch, ..) w/ a small unit test.

Great to see graph gets adopted!

Thank you!

Thank you so much Sven. Your workaround solution works

I submitted the bug report.

These are excellent news - thank you for sharing and testing!

Maybe you and your team can help fixing outstanding graph issues:

As mentioned earlier, pls inline all knowledge of this communication

I will give it a try

I'm back with the same problem unfortunately. I am now using a new computer (Ubuntu 15.04 with NVidia GTX 970). I moved my code from the old Mac computer to the new one and the workaround solution is giving me a runtime error . I get "com.jogamp.opengl.GLException: Program is not linked" for this line of code
renderState.setShaderProgram(gl, shaderProg);

Anyone know of a way I can trick it into working?

Thank you

Orthogonal issue, your shader code doesn't comply w/ ... (something).

If you use ShaderCode etc, you may want to set
property 'jogl.debug.GLSLCode' showing you the error line .. etc

Thank you Sven Gothel. I will try that but I'm wondering why it's a problem on one computer and not on another.
