How can we show a layout instead of tea pot model in vuforia sdk ImageTarget after image recognition

问题

How can we show a simple text i.e. "Hello" in a layout, if the the image is recognized in qualcomm vuforia sdk. i am using qualcomm vuforia sdk sample of ImageTarget, now it is showing a teapot after image is recognized. I am new in augmented reality. please help me.

回答1:

in JNI folder go to imagetarget.cpp file comment the Following things

#include "Teapot.h" 

this is the file that is loading a 3d Texture after that

 // Draw object:
    glBindTexture(GL_TEXTURE_2D, thisTexture->mTextureID);
    glTexCoordPointer(2, GL_FLOAT, 0, (const GLvoid*) &teapotTexCoords[0]);
    glVertexPointer(3, GL_FLOAT, 0, (const GLvoid*) &teapotVertices[0]);
    glNormalPointer(GL_FLOAT, 0,  (const GLvoid*) &teapotNormals[0]);
    glDrawElements(GL_TRIANGLES, NUM_TEAPOT_OBJECT_INDEX, GL_UNSIGNED_SHORT,
                   (const GLvoid*) &teapotIndices[0]);

for Vertices Comment the following lines

 glUseProgram(shaderProgramID);

    glVertexAttribPointer(vertexHandle, 3, GL_FLOAT, GL_FALSE, 0,
                          (const GLvoid*) &teapotVertices[0]);
    glVertexAttribPointer(normalHandle, 3, GL_FLOAT, GL_FALSE, 0,
                          (const GLvoid*) &teapotNormals[0]);
    glVertexAttribPointer(textureCoordHandle, 2, GL_FLOAT, GL_FALSE, 0,
                          (const GLvoid*) &teapotTexCoords[0]);

and this one

glDrawElements(GL_TRIANGLES, NUM_TEAPOT_OBJECT_INDEX, GL_UNSIGNED_SHORT, (const GLvoid*) &teapotIndices[0]);

that is to show the texture on the marker compile code using

ndk-build in Cmd 

and run the Teapot will not be shown and in on create show your own Text button the normal way of android
