The present application relates to virtual reality image processing technical field, disclose a kind of virtual reality ideological and political content adaptive generation method based on affective computing, comprising: user physiological signal is mapped as visual intervention weight coefficient;Preload reference and target color lookup table;In rasterization stage, the mask identification of information primitive is written to template buffer;In fragment shading stage, read template value, if matching mask identification, then weight is zero, otherwise keep weight;Based on weight, linear interpolation is performed on the sampling value of double lookup table, the present application realizes global atmosphere rendering and local information fidelity pixel-level decoupling by template buffer, solves the problem that key information is lost due to dynamic visual style reconstruction under constant computing power overhead.

In various examples, systems and methods are disclosed relating to quantifying the overlaps among a plurality of two-dimensional shapes. A system can identify a plurality of shapes for a circuit layout corresponding to an image. The system can allocate a stencil buffer for the image, the stencil buffer comprising a stencil sample for at least one point of the image. A system can generate, using the stencil buffer, an indication of a number of the plurality of shapes that overlap the at least one point. The overlap indications can inform alternative placements of the plurality of shapes for the circuit layout.

The invention relates to the technical field of virtual reality image processing, and discloses a virtual reality ideological and political content self-adaptive generation method based on emotion calculation, which comprises the following steps: mapping a user physiological signal into a visual intervention weight coefficient; preloading a reference color lookup table and a target color lookup table; writing a mask identifier of the information primitive into the template buffer area in a rasterization stage; reading a template numerical value in a fragment coloring stage, if the template numerical value is matched with a mask identifier, returning the weight to zero, otherwise, keeping the weight; according to the method, pixel-level decoupling of global atmosphere rendering and local information fidelity is achieved through the template buffer area, and the problem that key information is lost due to dynamic visual style reconstruction is solved under constant computing power overhead.
