    <p>I am trying to put a texture on a mesh, but failing. I am trying to render <a href="http://imgur.com/J9AaRzX" rel="nofollow">something like this, where texture can be seen</a> but I get <a href="http://imgur.com/Pl2lbBe" rel="nofollow">this</a>, where I can barely see the triangle. I am running the following code:</p> <pre><code>public class Game implements ApplicationListener{ Mesh mesh; ShaderProgram shader; Texture texture; public static void main(String[] args) { LwjglApplication app = new LwjglApplication(new Game(), "Mesh Tutorial 1", 800, 600, true); } protected static ShaderProgram createMeshShader() { String vert = Gdx.files.internal("data/VertexShader.txt").readString(); String frag = Gdx.files.internal("data/FragmentShader.txt").readString(); ShaderProgram.pedantic = false; ShaderProgram shader = new ShaderProgram(vert, frag); return shader; } @Override public void create() { if (mesh == null) { mesh = new Mesh(true, 3, 3, new VertexAttribute(Usage.Position, 3, ShaderProgram.POSITION_ATTRIBUTE), new VertexAttribute(Usage.Color, 4, ShaderProgram.COLOR_ATTRIBUTE), new VertexAttribute(Usage.TextureCoordinates, 2, ShaderProgram.TEXCOORD_ATTRIBUTE)); mesh.setVertices(new float[] { -0.5f, -0.5f, 0, 0.2f, 0.3f, 0.4f, 1f, 0, 1, 0.5f, -0.5f, 0, 0.1f, 0.2f, 0.1f, 1f, 1, 1, 0, 0.5f, 0, 0, 0.4f, 0.5f, 0.5f, 1f, 0 }); mesh.setIndices(new short[] { 0, 1, 2 }); texture = new Texture(Gdx.files.internal("data/badlogic.png")); } shader = createMeshShader(); } @Override public void render() { Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT); Gdx.gl.glEnable(GL20.GL_TEXTURE_2D); texture.bind(); mesh.render(shader, GL20.GL_TRIANGLES); } @Override public void resize(int width, int height) {} @Override public void pause() {} @Override public void resume() {} @Override public void dispose() {} </code></pre> <p>The <strong>Vertexshader</strong> is: </p> <pre><code>attribute vec4 a_position; attribute vec4 a_color; attribute vec2 a_texCoords; uniform mat4 u_projTrans; varying vec4 vColor; varying vec2 vTexCoord; void main() { vColor = a_color; vTexCoord = a_texCoords; gl_Position = u_projTrans * a_position; } </code></pre> <p><strong>Fragmentshader</strong>:</p> <pre><code>#ifdef GL_ES precision mediump float; #endif varying vec4 v_color; varying vec2 v_texCoords; uniform sampler2D u_texture; void main(){ vec4 texColor = texture2D(u_texture, v_texCoords); gl_FragColor = v_color * texColor; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
