Hi
I use of jpct for draw 3D model,2D model and text,I can complete 2D and 3D but in the draw a text i have a problem:
I use of this Link for tutorial
https://primalpond.wordpress.com/2013/02/26/rendering-text-in-opengl-2-0-es-on-android/
and this link for download project:
https://github.com/d3kod/Texample2
i set text in camera but i want when vuforia detect marker draw text,i don't know how can i calc matrix 4*4.
GLES20.glEnable(GLES20.GL_BLEND);
GLES20.glBlendFunc(GLES20.GL_ONE, GLES20.GL_ONE_MINUS_SRC_ALPHA);
Matrix.multiplyMM(mVPMatrix, 0, mProjMatrix, 0, mVMatrix, 0);
mVMatrix=modelViewMat;
glText = new GLText(mActivity.getAssets());
glText.load( "Roboto-Regular.ttf", 14, 2, 2 );
// TEST: render the entire font texture
glText.drawTexture( width/2, height/2, mVMatrix); // Draw the Entire Texture
glText.begin( 0.0f, 0.0f, 1.0f, 1.0f, mVMatrix ); // Begin Text Rendering (Set Color BLUE)
glText.draw( "More Lines...", 50, 200 ); // Draw Test String
glText.draw( "The End.", 50, 200 + glText.getCharHeight(), 180); // Draw Test String
glText.end();
"Matrix.multiplyMM()" Multiplies two 4x4 matrices together and stores the result in a third 4x4 matrix.
help me please
You are not supposed to mix direct calls to GL with jPCT-AE unless you absolutely have to. In this case, you actually don'thave to. There should be a link to the GLFont class in a sticky topic here in the forum.
could you please send me that link?
because i search and did't find it.
thanks
It's right on the first page of the jPCT-AE as a sticky topic. I can't post the link, because i'm on mobile only ATM and this gprum sucks on mobile when it comes to inserting links.
I find that.
