Get a stereo view

There are four stereo modes available in Olex2:

• Color stereo (resulting in monochrome stereo image)

• Anaglyph stereo (resulting in grey-scale color for colors matching with colors of the glasses)

• Rendering of two spatially separated projections

• Hardware stereo

The first three modes do not put any constraints on the hardware besides that the graphics card should be able to render two image of the scene with convenient frames per second (fsp). These modes work with ‘standard’ red-green or cyan-blue glasses.

The hardware 3D stereo requires special graphics card and 3D stereo glasses. A test stand we have to demonstrate the hardware 3D stereo is built using the following components:

? ? √?120Hz refresh rate display (we have Samsung)

? ? √?NVIDIA? 3D active shutter glasses (we have NVIDIA 3D vision kit)

? ? √?NVIDIA? Quadro FX graphics card (we have the low end FX580)

The standard NVIDIA? 3D vision kit is designed for the games and works only with the DirectX? based games (it is Windows? specific too). The Quadro series of the graphics cards provide a generic, OpenGL? based, portable mechanism for the 3D stereo rendering.

To switching stereo mode on/off use either the View tab of the GUI, or the following command:

>>gl.Stereo({none, cross, color ,anaglyph, hardware, interlace}, [angle=3]),

by providing the angle argument the viewing angle can be changes, the angle is signed and by inverting the sign the left and right projections are swapped.

To change the projection colours use the following command:

>>gl.StereoColor({lef,right}, R,G,B[,A])

R,G,B and A (optional) are the color components, floating point numbers in range of [0,1]. For example to set color of the left (mind the note above about the viewing angle) projection to red and of the right projection to cyan colors:

gl.StereoColor(left,1,0,0)

gl.StereoColor(right,0,1,1)

譯文如下：

3.4.3.?獲取立體視圖

Olex2中有四種可用的立體模式：

·Color stereo(產(chǎn)生單色立體圖像)

·Anaglyph stereo(產(chǎn)生與眼鏡顏色匹配的灰度顏色)

·兩個(gè)空間分離投影的渲染

·Hardware stereo

前三種模式對硬件沒有任何限制，顯卡應(yīng)該能夠以容易達(dá)到的幀率(fsp)渲染場景的兩個(gè)圖像。這些模式適用于“標(biāo)準(zhǔn)”紅綠或青藍(lán)眼鏡。硬件3D立體要求特殊的顯卡和3D立體眼鏡。經(jīng)測試演示硬件3D立體的測試臺(tái)必須由以下組件構(gòu)建：

√ 120Hz刷新率顯示器(我們用的是三星)

√ NVIDIA? 3D主動(dòng)快門眼鏡(我們用的是NVIDIA 3D視覺套件)

√ NVIDIA? Quadro FX顯卡(我們用的是低端FX580)

標(biāo)準(zhǔn)的NVIDIA 3D視覺套件是為游戲設(shè)計(jì)的，僅適用于基于DirectX?的游戲(它也是Windows?指定的)。Quadro系列顯卡提供了一種基于OpenGL?的通用便攜式3D立體渲染機(jī)制。

立體模式開啟/關(guān)閉的切換可以使用GUI中的View工具條，或者使用以下指令：

>>gl.Stereo({none, cross, color, anaglyph, hardware, interlace}, [angle=3])

通過提供角度參數(shù)可以更改視角，角度是有符號的，通過反轉(zhuǎn)符號，左右投影可以互換。

若要更改投影顏色請使用以下指令：

>>gl.StereoColor({left,right},R,G,B[,A])

R, G, B和A(可選)是顏色分量，浮點(diǎn)數(shù)的范圍為[0, 1]。例如，要將左側(cè)(請注意上面有關(guān)視角的注釋)投影的顏色設(shè)為紅色，將右側(cè)投影的顏色設(shè)置為青色：

gl.StereoColor(left,1,0,0)

gl.StereoColor(right,0,1,1)
