Thank you for presenting the information
I'm trying, but I haven't done it yet.
The TML text of Vuforia Studio only describes the vertex shader and fragment shader. Is this feasible?
It is the content that I am trying variously
I'm aiming for a look similar to a wireframe, but it's a little different.
<script name="testShader2" type="x-shader/x-fragment">
precision mediump float;
varying vec4 vertexCoord;
void main() {
float sinx = sin(400.0 * vertexCoord.x);
float siny = sin(400.0* vertexCoord.y);
float alpha = step(0.85, 1.0 - abs(sinx*siny));
vec3 black= vec3(0.0);
gl_FragColor = vec4(black,alpha);
}
</script>
<script name="testShader2" type="x-shader/x-vertex">
attribute vec4 vertexPosition;
varying vec4 vertexCoord;
uniform mat4 modelViewProjectionMatrix;
void main() {
gl_Position = modelViewProjectionMatrix * vertexPosition;
vertexCoord = gl_Position;
}
<script name="Xray" type="x-shader/x-fragment">

const float edgeFalloff = 0.8;
const float intensity = 1.0;
const float ambient = 0.2;
void main() {
vec4 color = vec4(r,g,b,1.0);
float opacity = abs(dot(normalize(-N), normalize(-I)));
opacity = abs(opacity);
// gl_FragColor = opacity * color;
if(opacity<thre)
{
gl_FragColor = vec4(r,g,b,opa1);
gl_FragColor.a=opa1;
}
else
{
gl_FragColor = vec4(1.0,1,1,opa2);
gl_FragColor.a=opa2;
