The internet is unconsciously transforming our brains and losing our ability to read and think deeply. Our attention is now so fragmented fragmented-focused on doing things, sometimes it has become a scarce capacity. But focusing on work and life is an indispensable ability. How to cultivate it? Here are some actionable suggestionsWe each have a head like this, a lot of direction, often wandering.Driven by infinite ideas, we never have enough time, because you always don't know where you spend y

Recent project requirements make a vision part of a scene. Just try to use UE4 's Landscape. But directly in the Editor to brush the terrain is too much work, brush out the terrain is not real, the most important thing is that the Landscape tool is not so useful.So we decided to use Worldmachine as a tool for terrain generation, to import the height map of the terrain into editor, and then to modify the details in the editor. Worldmachine generated by the height of the figure is relatively artif

Test Instructions/description: Dr. T has recently been studying a magical wind.This wind has a source, called the "Tuyere". The wind in the tuyere is either clockwise or counterclockwise.This kind of wind has energy.This wind is able to spread, if the wind can be spread around the tuyere, the wind will be like this to produce the next level of wind: (arrows indicate the direction of the wind, the most middle is the tuyere, the wind is clockwise, the wind in the Tuyere is counterclockwise, the s

With the development of economy and the progress of science and technology, intelligent robot is not a new thing. and the indoor service robot as a newly developed industry, gradually become the current industry, from the earliest start of the sweep robot, family accompany robot, feeding robot, etc. into the public eye. How to realize the autonomous positioning and navigation of mobile robot in uncertain environment has always been a core problem of robot research, and laser slam technology has

, need to consider a number of factors ( different weights , different stages of the importance of change ), and then the impact of factors need to be converted to a numerical measure .To simplify the model, we introduce the evaluation function g (s), s for the current situation, and g (s) to evaluate the current situation.G (s) = A1 * F1 (s) + A2 * F2 (s) + ... + an * FN (s)Note: Fi (s) is a scoring factor for an assessment , and AI is weightedThe introduction of the evaluation function g (s),

Flexpart is a hysplit-like diffusion pattern, its output netcdf file refers to the WRF, but the global properties are not written, such as only a projection name (such as Lambert), there is no relevant projection parameters: central longitude, standard latitude and so on. The WRF header file must be consulted to reconstruct the projection (why not tiger the property all over?). ）。 The latitude and longitude coordinates of the data are some, but the coordinates under the Lambert projection are no

projection (Universal spherical polar projection) for polar regions. Gaussian-gram gauss–krüger projections typically have a 6-degree range or 3-degree projection, which increases after 6 degrees. Usually used to make large scale map projection, such as 1/500,000, 1/100,000, 1/50,000, 1/10,000, etc. The projection method is named transverse_mercator,5 common parameter 3.4 albersprojection (Albers equal area projection) Albers equal product conic projection (albersequalarea conic) is a two-stan

When I read it, I found that some of the things I was trying to explain were the ones that I had never expressed. Now I will combine some of my ideas to make a stand to share with you.

screen, taking into account the whole map, so set for the 15*20 screen, so the height of the lattice: 15*800/128=94 width of the lattice: 20*600/128=94. 2, the puzzle when the reference map, but as far as possible to consider more, some of the changes in topography to be reasonable. Change the figure of the connection to twists and turns smooth, avoid square. 3, try not to use a kind of element in the same screen repeatedly, this will cause very ugly

topography, the eight-fork tree is better, but the cost is the reduction of efficiency. To some extent, the eight-tree can fully realize both indoor and outdoor terrain, and can combine the two, for this point, foreign researchers have achieved. But because of the efficiency of the consideration, still feel that should be based on the different types of game scenes to choose their own different management mode and connected together. In general, the
