It shows a landscape scene to which a pseudo-3D texture has been applied. A series of layers are defined in a texture map that describe landscape appearance at difference elevations. A position-based texgen is used with an indirect texture to select the blend of layers that should be applied at any given elevation.</P> 15 16<H2>Coverage</H2> 17<TABLE border="1" cellpadding="3" cellspacing="0.1" width="640"> 18 <TBODY> 19 <TR> 20<TD width="30%" bgcolor="#C0C0C0"><EM><STRONG>Functions</STRONG></EM></TD> 21<TD width="25%" bgcolor="#C0C0C0"><EM><STRONG>Parameters</STRONG></EM></TD> 22<TD width="45%" bgcolor="#C0C0C0"><EM><STRONG>Description</STRONG></EM></TD> 23 </TR> 24 <TR> 25<TD width="30%" rowspan="4"><CODE><A href="../../../gx/TexCoordGen/GXSetTexCoordScaleManually.html">GXSetTexCoordScaleManually</A></CODE></TD> 26<TD width="25%"><SPAN class="argument">Texture coordinates</SPAN></TD> 27<TD width="45%"><CODE>GX_TEXCOORD0</CODE></TD> 28 </TR> 29 <TR> 30<TD width="25%"><SPAN class="argument">Enabled</SPAN></TD> 31<TD width="45%"><CODE>GX_TRUE</CODE></TD> 32 </TR> 33 <TR> 34<TD width="25%"><SPAN class="argument">Scale S</SPAN></TD> 35 <TD width="45%">63</TD> 36 </TR> 37 <TR> 38<TD width="25%"><SPAN class="argument">Scale T</SPAN></TD> 39 <TD width="45%">63</TD> 40 </TR> 41 <TR> 42<TD width="30%"><A href="../../../gx/Indirect/GXSetNumIndStages.html"><CODE>GXSetNumIndStages</CODE></A></TD> 43<TD width="25%"><SPAN class="argument">Number of stages</SPAN></TD> 44 <TD width="45%">1</TD> 45 </TR> 46 <TR> 47<TD width="30%" rowspan="3"><A href="../../../gx/Indirect/GXSetIndTexOrder.html"><CODE>GXSetIndTexOrder</CODE></A></TD> 48<TD width="25%"><SPAN class="argument">Indirect stage</SPAN></TD> 49<TD width="45%"><CODE>GX_INDTEXSTAGE0</CODE></TD> 50 </TR> 51 <TR> 52<TD width="25%"><SPAN class="argument">Texture coordinates</SPAN></TD> 53<TD width="45%"><CODE>GX_TEXCOORD1</CODE></TD> 54 </TR> 55 <TR> 56<TD width="25%"><SPAN class="argument">Texture map</SPAN></TD> 57<TD width="45%"><CODE>GX_TEXMAP1</CODE></TD> 58 </TR> 59 <TR> 60<TD width="30%" rowspan="3"><A href="../../../gx/Indirect/GXSetIndTexCoordScale.html"><CODE>GXSetIndTexCoordScale</CODE></A></TD> 61<TD width="25%"><SPAN class="argument">Indirect stage</SPAN></TD> 62<TD width="45%"><CODE>GX_INDTEXSTAGE0</CODE></TD> 63 </TR> 64 <TR> 65<TD width="25%"><SPAN class="argument">S scale</SPAN></TD> 66<TD width="45%"><CODE>GX_ITS_1</CODE></TD> 67 </TR> 68 <TR> 69<TD width="25%"><SPAN class="argument">T scale</SPAN></TD> 70<TD width="45%"><CODE>GX_ITS_1</CODE></TD> 71 </TR> 72 <TR> 73<TD width="30%" rowspan="10"><A href="../../../gx/Indirect/GXSetTevIndTile.html"><CODE>GXSetTevIndTile</CODE></A></TD> 74<TD width="25%"><SPAN class="argument">TEV Stage</SPAN></TD> 75<TD width="45%"><CODE>GX_TEVSTAGE0</CODE>, <CODE>GX_TEVSTAGE1</CODE></TD> 76 </TR> 77 <TR> 78<TD width="25%"><SPAN class="argument">Indirect stage</SPAN></TD> 79<TD width="45%"><CODE>GX_INDTEXSTAGE0</CODE></TD> 80 </TR> 81 <TR> 82<TD width="25%"><SPAN class="argument">Tile size S</SPAN></TD> 83 <TD width="45%">64</TD> 84 </TR> 85 <TR> 86<TD width="25%"><SPAN class="argument">Tile size T</SPAN></TD> 87 <TD width="45%">64</TD> 88 </TR> 89 <TR> 90<TD width="25%"><SPAN class="argument">Tile spacing S</SPAN></TD> 91 <TD width="45%">0</TD> 92 </TR> 93 <TR> 94<TD width="25%"><SPAN class="argument">Tile spacing T</SPAN></TD> 95 <TD width="45%">64</TD> 96 </TR> 97 <TR> 98<TD width="25%"><SPAN class="argument">Indirect texture format</SPAN></TD> 99<TD width="45%"><CODE>GX_ITF_4</CODE></TD> 100 </TR> 101 <TR> 102<TD width="25%"><SPAN class="argument">Indirect texture matrix</SPAN></TD> 103<TD width="45%"><CODE>GX_ITM_0</CODE></TD> 104 </TR> 105 <TR> 106<TD width="25%"><SPAN class="argument">Indirect bias select</SPAN></TD> 107<TD width="45%"><CODE>GX_ITB_NONE</CODE>, <CODE>GX_ITB_T</CODE></TD> 108 </TR> 109 <TR> 110<TD width="25%"><SPAN class="argument">Bump alpha select</SPAN></TD> 111<TD width="45%"><CODE>GX_ITBA_OFF</CODE>, <CODE>GX_ITBA_S</CODE></TD> 112 </TR> 113 </TBODY> 114</TABLE> 115 116<H2>Using the Demo</H2> 117<P>START ends the demo.<BR>The main stick rotates the model.<BR>The substick translates the model.<BR>The A/B buttons zoom in/zoom out.</P> 118 119<H2>Snapshot</H2> 120<P><IMG src="./images/ind-pseudo-3d-0.jpg" alt="ind-pseudo-3d-0.jpg (32533 bytes)" width="640" height="448"></P> 121<P><IMG src="./images/ind-pseudo-3d-1.jpg" alt="ind-pseudo-3d-1.jpg (21990 bytes)" width="640" height="448"></P> 122<P><IMG src="./images/ind-pseudo-3d-2.jpg" alt="ind-pseudo-3d-2.jpg (21932 bytes)" width="640" height="448"></P> 123 124<H2>Required Data Files</H2> 125<P><CODE>$REVOLUTION_SDK_ROOT/dvddata/gxTests/pseudo.tpl</CODE></P> 126 127<H2>Revision History</H2> 128<P> 1292006/03/01 Initial version.<br> 130</P> 131 132<hr><p>CONFIDENTIAL</p></body> 133</HTML>
