    <p>I don't know If I understend you correctly. Texturing is described well in <a href="http://www.glprogramming.com/red/chapter09.html" rel="nofollow noreferrer">redbook</a>. They use GLUT in the book, so you should find the answer in the examples.</p> <p>In short: call glTexCoord2f(u,v) before call to glVertex (if you do not use VBO), where u,v are texture coordinates.</p> <p>HTH</p> <p>EDIT: Sorry, now I understand the question. </p> <p>I have never used tesselators, but maybe I can help :-)</p> <p>Tesselators only find points where new vertices should be created. Standard glVertex is used to send them to the GPU. </p> <p>You can use your own function to draw vertex. If you register callback with</p> <pre><code>gluTessCallback(tobj, GLU_TESS_VERTEX, (GLvoid (*) ()) &amp;vertexCallback); </code></pre> <p>then your function is called every time new vertex is created. You can also use </p> <pre><code>gluTessCallback(tobj, GLU_TESS_COMBINE, (GLvoid (*) ()) &amp;combineCallback); </code></pre> <p>to add some information to the vertex - like normals, colors, tex coordinates.</p> <p>See <a href="http://www.glprogramming.com/red/chapter11.html" rel="nofollow noreferrer">redbook - chapter11</a> example 11-2</p> <pre><code>/* a different portion of init() */ gluTessCallback(tobj, GLU_TESS_VERTEX, (GLvoid (*) ()) &amp;vertexCallback); gluTessCallback(tobj, GLU_TESS_BEGIN, (GLvoid (*) ()) &amp;beginCallback); gluTessCallback(tobj, GLU_TESS_END, (GLvoid (*) ()) &amp;endCallback); gluTessCallback(tobj, GLU_TESS_ERROR, (GLvoid (*) ()) &amp;errorCallback); gluTessCallback(tobj, GLU_TESS_COMBINE, (GLvoid (*) ()) &amp;combineCallback); /* new callback routines registered by these calls */ void vertexCallback(GLvoid *vertex) { const GLdouble *pointer; pointer = (GLdouble *) vertex; glColor3dv(pointer+3); glVertex3dv(vertex); } void combineCallback(GLdouble coords[3], GLdouble *vertex_data[4], GLfloat weight[4], GLdouble **dataOut ) { GLdouble *vertex; int i; vertex = (GLdouble *) malloc(6 * sizeof(GLdouble)); vertex[0] = coords[0]; vertex[1] = coords[1]; vertex[2] = coords[2]; for (i = 3; i &lt; 7; i++) vertex[i] = weight[0] * vertex_data[0][i] + weight[1] * vertex_data[1][i] + weight[2] * vertex_data[2][i] + weight[3] * vertex_data[3][i]; *dataOut = vertex; } </code></pre> <p>It should be sufficient to bind texture as usually - do it before drawing with tesselators.</p> <p>HTH</p>

    1. COBut when you use GLUTess you cannot make calls before each vertex hence my issue

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.
