介紹

Lenscare 將景深和焦點生成移到後期製作。如果您需要具有 2d 後期處理靈活性的高質量相機模糊,Lenscare 是一個不錯的選擇。它可以讓您擺脫冗長的額外 3d 渲染時間。這些過濾器開發過程中的關鍵方面是盡可能匹配真實的東西。 Lenscare 可作為 Adob​​e After Effects 和 Photoshop 兼容程序的插件使用。

景深

景深效應(dof)在所有真實的光學器件中都在一定程度上發生。它作為一種風格元素被大量用於攝影和電影中。在計算機圖形中,dof 通常使用光線追踪技術生成,這會大大增加渲染時間。景深插件可以快速生成這些作為後期處理。它需要一個深度緩衝區來進行計算。

失焦

“失焦”是一個沒有深度信息的快速版本。它會在整個圖像上創建一個具有恆定半徑的模糊,並且是對“景深”的很好補充。它還提供了一些額外的功能。除了可生成的鏡頭外,還可以使用自定義繪製的鏡頭。“失焦”還為半透明區域提供背景失真。

Out of Focus 用於電影 Imposter 中的現場和 cgfootage。
相機模糊看起來與普通模糊過濾器的外觀大不相同。除其他差異外,Lenscare 還提供以下功能以幫助增加真實感:

鏡頭光圈

相機鏡頭光圈極大地定義了其模糊(散景)的外觀。因此,過濾器提供了改變鏡頭孔徑形式以模擬多種真實相機的可能性。如果您想將 CG 元素合成到真實鏡頭中,或者只是想讓您的 CG 鏡頭與其他元素相適應,這一點很重要。可以模擬各種孔徑。Out of Focus 插件提供了用自定義圖像完全替換光圈的可能性。光圈的形式在高光點最為明顯。

強調

實際上,在失焦時非常明亮的圖像部分占主導地位。不幸的是,常見的圖形格式削減了明亮的部分。因此,插件提供了選擇應該更亮的部分並給予這些提升的可能性。

背景失真

這僅在“失焦”中可用。當透過模糊的物體看時,背景會因該物體而變形。這個效果不是很明顯。但是輕微的扭曲有助於增加你的伴奏的可信度。要體驗這種效果,請嘗試將手指放在眼前,使其散焦。現在通過模糊區域查看後面的任何內容。稍微移動手指以更好地查看效果。
Lenscare 提供多種選項來調整鏡頭孔徑以匹配特定外觀。
除了速度和質量之外,景深後置濾鏡的一個重要優勢是您可以輕鬆測試各種焦點設置,而無需重新渲染整個場景。這樣您就可以快速了解哪些設置最適合您的拍攝。

速度

“失焦”效果是一種快速的二維模糊,可以與任何現有解決方案相媲美。“景深”的速度非常快。在很多情況下,您可以在後期處理中節省數小時的渲染時間,每幀只需幾秒鐘。這是一個很大的優勢,尤其是對於高質量的全局照明渲染。想像一下您可以在動畫上節省多少。當然,如果存在,Lenscare 會利用多個 CPU。

質量

提供大量景深和散焦解決方案。對我們來說幸運的是,大多數人都沒有正確地模擬相機效果。他們的名字並不公正,因為他們的算法不是基於物理的。它們只是在某些情況下看起來不錯但在其他情況下失敗的方法。“景深”濾鏡的一個常見錯誤是“模糊”所有周圍的像素而不考慮它們的深度值。通常這會在深度差異很大的區域產生醜陋的發光效果。在 After Effects 版本中可以很好地看到上述工件。請注意,After Effects 版本經過誠實調整,看起來盡可能好。如果沒有使用足夠的樣本,隨機或超級採樣光線追踪模糊會出現偽影。Lenscare 不會產生任何此類偽像。當然兩個濾鏡都支持16位圖像格式。

問題

所有後處理景深解決方案都有一個共同的不可避免的問題。無法正確模糊透明物體後面的反射或物體。當您看到深度緩衝區每個像素只能保存一個值時,這一點就很明顯了。但最大的問題無疑是信息缺失。“景深”試圖彌補缺失的信息,但當然在某些情況下這還不夠。一個說明該問題的示例是攝像機前面的柵欄,該柵欄嚴重失焦,以至於在生成的圖像中幾乎看不出來。現在該插件必須完全彌補該柵欄後面的內容。顯然這是不可能的。

Flair

Flair brings 8 high quality effects to Adobe After Effects and Photoshop compatible programs. Among them shine, glow and sparkle effects. Of course with 16bit and multi CPU support.

Amiga RulezThis effect is an old demo coders effect which has been used plenty in Amiga demos and was also simply called Zoom Rotator. I saw it first in an Amiga 500 demo by Sanity where it’s coder Chaos did an incredible job making it realtime in fullscreen. The image shown was just a text saying ‘Amiga Rulez’ because the demo entered a competition held by Commodore at the World of Amiga 92. Later many extensions to this effect have been made such as making it rotate around 3 axis instead of only one like the original effect.
Box BlurThis is a sub pixel accurate Box Blur. It includes an aberrative mode which splits colors as can be seen in the example image. Included is the option to operate the filter with a mask that determines blur on a per pixel base.
Abberative mode with soft mask.
 
Glass SphereA shiny glass sphere with lots of options to adjust material, lighting and refraction. Nice for making homepage menu knobs 😉
 
Mosaic PlaneThis is an extension of the well known mosaic effect. The mosaic is applied to a virtual plane which can be freely rotated and positioned. Operate it with a mask to alter rotations or size on a per pixel base.
Funky?
 
GlowThe Glow Plugin provides 4 different algorithms to generate fast beautiful glows from a existing footage. All methods work with sub pixel accuracy so there is no popping effect when animating the radius unlike with other glow effects. It’s possible to determine which areas are to glow in what intensity. There are various parameters to adjust the effect to your needs including color adjustment, gamma correction, aspect, aspect angle and several blend modes.
 
HighlightGenerates sparkling light streaks from existing footage. Offers the possibility to determine the sparkling areas and their intensities. There are various Parameters to adjust the effect to your needs. Including radius, intensity, color adjustment, gamma correction, streak count, and blend mode. Again this effect is sub pixel accurate for animations.
 
Radial BlurThis is a fast high quality radial blur. It features a ‘aberrative’ mode which splits colors. This mode roughly simulates the effect of a camera lens aberrating the incoming light into their spectral components (like in a prism). This effect can be observed at bad cameras and special lenses. Decent usage can add some realism to cg renders.
Radical Blur.
 
VolumetricsThis one lets you create blazing fast impressive light effects. Volumetrics simulates light passing through your footage. It’s possible to determine a per pixel transparency for the light. Two different algorithms are available which basically give the same results but differ in smoothness of the casted light. Though the effect looks very much like true volumetric light it’s actually a 2d effect.There are various parameters to adjust the effect to your needs. Including color adjustment, gamma correction, ray length, radius and several blend modes. Not only compared to the traditional method of generating Volumetric light using a raytracer our solution is blazing fast.
 

Fresh Curves

Introduction

Curves are a very versatile and precise color correction tool. The native After Effects version lacks control and accuracy to take full advantage of it. Fresh Curves makes up for these drawbacks so you can get the most out of this basic tool.

More control

More channels
Fresh Curves has brightness, saturation and hue channels for more direct control on top of the usual RGBA.

Relative Curves
Now it’s possible to adjust on attributes based on another. Relative Curves also has a built-in preblur and a postblur curve.

Bezier cubic splines
with tangent handles for more curve control. Interpolation modes similar to the ones in the AE graph editor round things off.

Invert Curves
Using invert you can work in your own color space. Apply your custom “gamma curve”, do the work and apply and the inverted one.

More accuracy

Histogramm
The integrated histograms helps you find and modify desired areas and gives feedback to your changes.

Interface
Tired of that old, tiny interface? Here is a big, nice resizeable one.

Zoom tools
will come in handy for those out of range float colors or when fiddeling with details.

Edit and sample
Need to be precise? Just edit or sample your values. And change the color range to what you are comfortable with.

ZbornToy

ZbornToy – the after effects plugin

Our debut product is made to lead a line of tools that introduce a new meaning to depth in compositing. The ZbornToy has the ability to extract a maximum of information out of simple depth images and allows you to not only light and texture them, but to refract backgrounds, cast caustic reflection back onto the background and a whole lot more.  

The design of ZbornToy has the amount of parameters reduced to a minimum, while still providing a vast amount of control over every aspect of it. The goal has been to achieve the performance and feel of a full blown render engine when it comes to the results. Yet it is ment to be not only easily accessible, but fast and fluent so that it is fun and even playful to use. 

 

Lighting supports shadows and soft shadows and is kept within the plugin for a maximum portability to other compositing packages that support after effects plugins. Sources of light are by means of a direct light, a point light and environmental illumination. The environmental illumination is based on panoramic or spherical maps. It includes occlusion approximations and independent reflection settings. The reflection is directly tied together with the shading section and gets diffused and colored according the surface definitions. 

 

The shading section offers a set of innovations that simplify the shading process dramatically, while keeping the look of the surfaces stunningly coherent. For example, defining the glossiness of a surface requires nothing more than to dial or texture the glossiness parameter. Everything related to the look of a glossy surface automatically responds accordingly based on both mathematical and artistic understanding of the required process. The amount of paramters is destilled down to a minimum while maintaining a maximum of flexibility to easily create all sorts of materials ranging from the usual plastics over metal to particularely skin, supporting translucency in the easiest to use ways ever.

And all of the above is computing practically at realtime. Taking advantage of After Affect’s adaptive previews, you can dial in your paramters and adjust lighting and textures while looking at the results. We are very used to having medium resolution renders (800×800) done within 1 to 3 seconds per frame.

A final quality section allows for high profile results through a set of innovations in reading and projecting refractions and alternative oversampling options.
