Abstract
The invention provides a method for controlling lighting through three-dimensional software, which comprises the following steps of: making a virtual model corresponding to an actually-shot object in the three-dimensional software, and associating corresponding sampling points of the virtual model and an actually-shot model; making animation in the three-dimensional software by using the virtual model according to the lighting effect which the actually-shot object needs; and playing the animation, and sending light intensity data of the sampling points on the virtual model in each frame to a light array to adjust the lighting of the light array according to the light intensity data.
Description
Technical field
The present invention relates to a kind of lamp light control method, particularly a kind of method of utilizing three-dimensional software control light.
Technical background
Though it is not long that computer graphical is made the industry generation time, really be the irrealizable picture of scene because it can realize many, so development speed is quite swift and violent.
Films and television programs even content that may 80% are all finished by computer photograph.And this is wherein in order to allow picture look truer, and a lot of things all are that actual situation is in conjunction with handling.Usually need scene and three-dimensional body coupling with actual photographed in the production of film and TV, wherein the light coupling is a kind of process of complicated and time consumption.In order to make the three-dimensional part of making and the complete combination of personage of actual photographed, in the direction of light, color, aspects such as brightness then will be consistent.This need rely on artistical sensation to be adjusted repeatedly, and the complicated lighting effects of dynamic change almost can't be mated.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of method of three-dimensional software control light, be used to address the above problem.
In order to achieve the above object, the invention provides a kind of method of three-dimensional software control light, it may further comprise the steps:
The present invention adopts Maya synchronizing lamp photosystem, can be directly by in Maya, making animation, and driven in synchronism exterior light battle array has then been abandoned the method for original estimation light, makes light control become very easy, realizes the perfect adaptation of actual situation light.The present invention can also expand and be used for light of stage, light such as virtual reality control field.
Description of drawings
Fig. 1 is the flow chart of a specific embodiment of method of a kind of three-dimensional software control of the present invention light;
Fig. 2 is the schematic diagram of a specific embodiment light of the present invention battle array.
Embodiment
Please referring to shown in Figure 1, the invention provides a kind of method of three-dimensional software control light, it may further comprise the steps.
In a specific embodiment, described dummy model has identical size or equal proportion with the real scene shooting object.Controlling like this can be more convenient, is unlikely to occur mistake.
The sampled point of associated virtual model and real scene shooting object can allow photometry more accurate.The intensive more relative result of sampled point is more accurate, but inevitable amount of calculation can increase much the real-time variation.
Traditional mode is artificial control light, and the unavoidable bad intensity of illumination angle of control that occurs on the operation opportunity when holding bad light and changing, is very easy to occur the excessive situation of operation.And the lighting effects of object to be shot are made animation, guaranteed the standardization of action, have simultaneously can be well with picture in other guide merge.
In a specific embodiment, described three-dimensional software is Maya.Described light battle array is by the control circuit control of microprocessor controls, described microcontroller is calculated after receiving the light intensity data that described three-dimensional software provides, obtain the brightness and the color of light on the light battle array, the microcontroller Drive and Control Circuit changes the brightness and the color of light on the light battle array.
Concrete steps comprise that microcontroller sends the mel order of the rgb light strength component that obtains each sampling point position by mode and the Maya communication of similar soket to Maya.When receiving after Maya calculates the return value finish, microcontroller is translated into specific coding and sends on the control circuit by interface.
In a specific embodiment, described Maya sends on the microcontroller by the USB mouth after having calculated sampled point luminous intensity component.
As shown in Figure 2, described light battle array is a spherical structure in a specific embodiment, and the light on the described light battle array is the LED lamp, and described LED lamp is uniformly distributed on the surface of spherical structure.Described real scene shooting object is in the position of the centre of sphere.Microcontroller adopts the pulse-width modulation coding, and by modulating pulse duty ratio control LED brightness, the rgb light strength component that Maya is sent converts the switch brightness control signal to, the control control circuit.
In like manner, adopt method of the present invention to expand and be used for light of stage, light such as virtual reality control field.
The above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement etc., all should be included within protection scope of the present invention.
