Hi everyone,
I have very recently started using the Coolux server and have been set a project that I am having trouble with and would really appreciate any advice that could help me solve the issues that I am coming up against.
For the event I have to project onto the ceiling of a ballroom the dimensions of which are roughly 30m long by 15m wide with semi circular ends to the ceiling to add another layer of complication the ceiling is a typical convex dome shape. The projectors (20k Christie roadsters) will be on a balcony roughly 4m from the ground floor and the same amount from the apex of the ceiling, they will be at apposing ends of the ballroom shooting down the length of the ballroom. The content to be shown on the ceiling will be a flag gently blowing in the 'wind'.
I have used other projection systems to deal with multiple projection blends on flat front and rear projection surfaces, but this cross projection warping onto a convex domed ceiling is really blowing my mind.
I have mocked the scenario in the office with two dektop projectors and listed below are the steps that I have taken, they definately are not correct I realise but as I mentioned this is new to me, I am hoping that it will be somethng simple that I have maybe not thought about and can easily fix?
I've got my coolux setup with a dual independant output I then open the warper software open a 5x5 FFD mesh and assign that to the sencond output then repeat that process for the first output. I then have turned the mesh on the first output on via the advanced menu by 90 degrees and then rotated the secondary output warp file by 270 degrees so that the two projections are on the same orientation, not sure if that is necessary but it seemed to make sense. I've then carried out all of the appropriate alterations to the to the FFD and mesh files untill they look correct. Then I export them as '.x' files after opening up my Manager software I drop the appropriate '.x' file to the correct output. For some reason the when I then place some content onto a layer the output bears no real resemblence to my altered '.x' warped files that I have just spent hours sorting out in the warper programme. On top of that the content is two seperate images not one continuous smooth flag, both starting in the centre of the projection.
I expect and hope that this is a relatively simple problem to over come, having watched some of the videos about coolux hopefully one of you legends will be able to point me in the right direction.
Much appreciarted
