Add touch event on specific augmented object on camera

By mihir92m on Fri, 01/02/2015 - 10:59

Hello guys, I'm working on such a application which augment image when camera detect target image using vuforia SDK in native android code. 

Here is a issue that I'm facing.

I want to move my image on touch. I have implemented touch event on surfaceview on which my image is augmented. So now wherever I move my finger on screen my image moves. But I want to implement touch event only for my image so when I touch or move my finger on rest of screen it should not make any effect on image.

 

Here is my code for augmenting image :::

 

 float[] modelviewmatrix = vuforiamatrix.getData();           Matrix.translateM(modelviewmatrix, 0, 0.0f+mXdistance, 16.5f+mYdistance,           17.0f);   Matrix.rotateM(modelviewmatrix, 0, 180.0f, 0.0f, 1.0f, 0.0f);           Matrix.scaleM(modelviewmatrix, 0,420+mDistance,                    420+mDistance, 420+mDistance);                      Matrix.multiplyMM(modelviewprojectionmatrix_image, 0, vuforiaAppSession                    .getProjectionMatrix().getData(), 0, modelviewmatrix, 0);       GLES20.glUseProgram(shaderProgramID_image);GLES20.glVertexAttribPointer(vertexHandle_image, 3, GLES20.GL_FLOAT, false, 0,              imageloader.getvertexbuffer());GLES20.glVertexAttribPointer(normalHandle_image, 3, GLES20.GL_FLOAT, false, 0,    imageloader.getnormalbuffer());GLES20.glVertexAttribPointer(textureCoordHandle_image, 2,           GLES20.GL_FLOAT, false, 0, imageloader.gettexbuffer());   GLES20.glEnableVertexAttribArray(vertexHandle_image);GLES20.glEnableVertexAttribArray(normalHandle_image);    GLES20.glEnableVertexAttribArray(textureCoordHandle_image);  GLES20.glActiveTexture(GLES20.GL_TEXTURE0);      GLES20.glBindTexture(GLES20.GL_TEXTURE_2D,texturehandler_image);GLES20.glBindTexture(GLES20.GL_TEXTURE_2D,texturehandler_image);    GLES20.glUniform1i(texSampler2DHandle_image, 0);   GLES20.glUniformMatrix4fv(mvpMatrixHandle_image, 1, false,           modelviewprojectionmatrix_image, 0);        GLES20.glDrawElements(GLES20.GL_TRIANGLES,            6, GLES20.GL_UNSIGNED_SHORT,            imageloader.getindicesbuffer());          GLES20.glDisableVertexAttribArray(vertexHandle_image);     GLES20.glDisableVertexAttribArray(normalHandle_image);     GLES20.glDisableVertexAttribArray(textureCoordHandle_image);
